I intend to release zc.buildout 1.5.0 Monday, August 23.
I used http://pypi.python.org/pypi/osc.recipe.sysegg/ to reliably grab
specific system python packages (PIL, matplotlib, etc). That one is
broken with 1.5.0, as it cannot find PIL and friends anymore.
Using the
http://svn.zope.org/repos/main/zc.buildout/branches/1.4/bootstrap/bootstrap.py
helps getting everything working (at least temporary).
osc.recipe.sysegg's problem is that a pkg_resources.require(egg) call
doesn't find any of the system eggs anymore. Am I correct that that's
one of buildout's changes? That the recipes are really totally isolated?

The workaround is of course to remove bin/buildout, do python2.4 bootstrap.py
and run bin/buildout again. So probably no big deal, but a bit unexpected
anyway.
OK, fair enough. Thanks for the report.
I'm inclined to agree with you that it is not a big deal. It sounds like you
need a resolution to the osc.recipe.sysegg problem more?
Ah, you confuse me with my evil twin brother Reinout. :-) Well, okay,
he is not evil and no twin, but he is my brother. The first part of the
mail (about osc.recipe.sysegg) was from him, and I reacted to that in
the second half with my own little problems.
To me it sounds like osc.recipe.sysegg should not be necessary anymore
when using zc.buildout 1.5.0 and zc.recipe.egg 1.3.2.
