(including Chaco and Mayavi2)
Comment:
I ran into some very annoying problems with this package, where it
appeared to build successfully but then failed to work. I can't recommend
this spkg (even for experimental) until something is done.
There were two separate issues. Both allowed an apparently successful
build which then failed to run. The first is that some X libraries were
not installed on my machine; when I tried to run mayavi2, I got the
{{{
pkg_resources.DistributionNotFound: EnthoughtBase>=3.0.2.dev
}}}
error described above.
Once that was fixed, mayavi2 still would not run; this time I got this
error:
{{{
ImportError: cannot import name cached_property
}}}
This time the problem was that I had installs of previous versions of
these spkgs in site-python. Once I removed those, I was able to
successfully install and run this spkg.
IMHO, the current status is not acceptable even for experimental. At
least, the package should detect at build time that it did not build
successfully (that mayavi2 cannot be run successfully), and fail the build
in this case; and also print out some useful text (Something along the
lines of "Try installing xorg-dev and removing old versions of this
package from site-python", but a bit more detailed and acknowledging the
existence of systems other than Debian/Ubuntu).
