By the way, it’s nice to hear that there are people which are really interested in trying Grapefruit out. It still makes me wonder at times that I’ve made something that other people find really useful. (Of course, I’ve not done Grapefruit alone but Matthias Reisner has also done a notable amount of work.) So I would really like to get feedback concerning peoples impressions about Grapefruit. Seeing interest in Grapefruit might give me more motivation for the work on it and therefore speed up its development. […] Anyway, three hours after wanting to try it out, grapefruit is up and running, and I did not even have to install its dependencies by hand. It seems like grapefruit could benefit from nestable cabal packages, though: It has one big script that installs many packages. You could also call them dependencies. You could create a basically empty package named “grapefruit” which just depends on all Grapefruit packages. Debian uses this concept for its packages.

No, wait, there's cabal-install. And it doesn't even depend on 20+

Ah, there it is:

* Bootstrapping Cabal...
no location info: can't find file: Setup.lhs

The ebuild for the darcs version of Cabal it out of date. This happens
frequently with *-darcs ebuilds because upstream changes.
http://hackage.haskell.org/packages/archive/cabal-install/0.4.0/cabal-install-0.4.0.tar.gz
This version is unfortunately far far too old. I cannot upload a new
version to hackage until I release Cabal-1.4 which it depends on.
Fortunately I'll be releasing both soonish and in the mean time you can
try the darcs versions or the pre-release tarballs from a few weeks ago.
Building works, installing too, but registering fails: the Makefile
does not seem to like --user:
% runhaskell Setup.lhs register --user

The wx package seems to be broken. It is registering directly with
ghc-pkg and not respecting the --user flag. This is because it uses make
rather than the build infrastructure that Cabal provides. Not that I can
blame it for that, it's a pretty complex package and Cabal doesn't yet
provide all the features it needs. Gtk2Hs is not cabalised yet either.
Just a second...
# emerge wxhaskell -pv
These are the packages that would be merged, in order:

In other words: No way. The only program that touches anything in /usr/
is portage.
It's trying to downgrade ghc because the version of wxhaskell in portage
only works with ghc-6.4.2 and not 6.6 or 6.8.
Rationale: We need a CPAN, a cabal that is smart enough to know what to
to, even if building depends on make, grapefruit authors that commit
to hackage, a cabal-inst that can install from darcs (or at least from
a local directory)
It can build from a local directory. Being able to build from darcs is
possible in principle but we've not implemented it yet.
, or maybe just a make-replacement for haskell, like
java has with ant (which is really cool if you successfully do not
notice the xml-syntax).
We're doing something like that as a Google Summer of Code project this
summer.
I would already shut up if there were an ebuild generator, but then I'm
not that egoistic ;)
There is. It's called hackport. We use it to generate most of the 100's
of Haskell ebuilds that you find in the haskell overlay.
So I fully appreciate this packaging stuff is sometimes frustrating. I
hope you appreciate that it is actually improving.
BTW, if you have specific bugs to report in Cabal, cabal-install or
hackage (ie hackage itself, not problems with packages in hackage) then
please do report them in our bug tracker:
http://hackage.haskell.org/trac/hackage/
You'll also find links there to the darcs versions of Cabal and
cabal-install if you want to play with them.

Re: [Haskell-cafe] Damnit, we need a CPAN.
I've been playing a lot with searchpath lately, for doing happs quickstart installation as described on happs.org. Searchpath works great when it works, which usually means -- when the module map file is up to date and pointing everywhere to the right place. When the module map file is out of date though, the error messages for missing dependencies that you would get from searchpath are not as good as the error messages you'd get from a cabal configure.
