I don't want to sound discouraging because this is an area with lots of room for improvement. A better conclusion: Ultimately, people want to integrate the various PMs with portage because portage is pretty good at keeping your system reliable, up-to-date, and secure. The language-specific PMs on the other hand only care about ease of use and how fast they can get bleeding-edge releases to you. Having both would be ideal, but if we simply shell out to the language-specific PM, then that would sidestep the good parts of portage making the integration pointless. The time and attention involved in ebuild packaging turn out to be critical parts of the product.

If somebody were willing to do the work I'm sure it would be useful if portage had a more generic interface for stuff like this, such as a way to do plugins/etc. The idea would be to run some outside package manager in some kind of sandbox, then create a binary package from what gets installed.

Have you ever tried to build it without using the release binaries? I suppose this is a second problem though, where people want to be "self-reliant" and instead just end up making things impossible to verify or make reproducible. For the longest time Cabal did not authenticate or verify the code it would run (as root).

Distributions are usually not binary compatible. This "works" by having each distribution customize and build a project by hand. 2) Virtualenv works well, and cabal now has a local installation option. Still, these are not perfect. 3) Use a git ebuild, or target stable versions. If a project has so much churn that I can't keep up with it I will find something more stable. 4) True, but prefix would be a lot better at fixing that problem. If not that, something like virtualenv. In the case of either #3 or #4, the distribution developers prefer you use their package manager to install packages. You are only safe doing anything else in an environment like virtualenv, which does not exist for the vast majority of languages. This is why developers will pass

It turns out this stuff exists because: 1) Upstream wants to push 1 single thing and have it work in all distros. 2) pip / virtualenv / cargo / whatever work reasonable well. 3) Rolling-based distros couldn't keep up with packaging. 4) Snapshot-based distros (debian stable / ubuntu) were not designed with this in mind as much; because packages were developed with a high velocity. > If you want to eliminate the duplication of effort, tell these people to > use Gentoo Prefix instead of writing the N+1st crippled PM.

I agree that in theory they could have published ebuilds for Gentoo prefix and it would have 'worked everywhere' but I think that boat sailed about 10 years ago. https://wiki.gentoo.org/wiki/Project:Perl/g-cpan is a project is in a similar space and basically reads perl CPAN metadata to generate stub ebuilds. Portage tracks these stub ebuilds (and so for example, it tracks what these cpan packages install and can remove them afterwards.) I think this is the most pragmatic approach I've seen used as its mostly an adapter (to cpan) that just generates ebuilds. Its plausible that with some careful eclass magic you might be able to make the installed packages compatible with pip, cargo, etc. I think its more of a struggle to make it compatible with things like virtualenv or pip --user though. -A

These other package managers don't solve any hard problems -- they're basically a fancy interface around wget and "git clone."

[gentoo-dev] Integrating Portage with other package managers
Having used Gentoo for a few years now, one thing that has been annoying to me is the tremendous duplication of effort and uphill battle of creating ebuilds (build recipes) for language-specific packages that already have their own build systems. For example, many languages such as Python (pip), Node (npm), Ruby (gems), TeXLive (tlmgr), Haskell (cabal), Rust (cargo) have ways of redistributing up-to-date dependencies and ensuring that they build properly in most environments. Portage, it seems, does not take advantage of this at all. If I want to install the package 'foo', which has 'bar' as a dependency (which has been installed through cabal, for instance). Why should portage download some outdated second copy of the sources for 'bar', rebuild it, and scatter it around the file system where it cannot be used by other programs installed by cabal? It seems reasonable to me to 'hook' portage into these other package managers, so that running 'emerge bar' would actually run 'cabal install bar' rather than downloading sources and running 'ghc'. This would make managing dependencies much easier as versions change, since most (all?) these alternate package managers have ways of specifying specific versions of packages or pinning. It would also put an end to the breakage caused by, for example, running 'pip' as root and breaking all the python libraries portage has pulled in. I also notice that there is a GSoC 2018 project for integrating Rust more closely within Gentoo. It seems to me that allowing ebuilds to be written like this would help resolve this not only for Rust, but for all languages with similar build systems (which is most modern languages, frankly). The only real issue I see with this is the potential loss of granularity with USE flags for some of these packages, but having poked around the sort of language-specific libraries and bindings available, hardly any have any USE flags available, and those that do only offer debug symbols or documentation, which many of these other build systems offer as well, so I doubt this would be an issue for anyone. I could of course be wrong. Is this a feature/improvement other Gentoo users/developers would be interested in? If so, I would love to help discuss and potentially help with its implementation.
