Also, I got some ways in making the buildbot build with numscons, but I 
stopped at a bug where it looked like the matplotlib.tests.* modules 
were not getting installed:

http://mpl-buildbot.code.astraw.com/builders/Ubuntu%208.04%2C%20Python%202.5%2C%20amd64%2C%20scons/builds/13/steps/test/logs/stdio

I haven't had a chance to debug this further, but I'm open to ideas. 
Also, this branch is building from a git repository (a mirror of David's 
which I can't clone normally, for some reason), for what it's worth.

I know it's been a while since you announced this, but I'm just looking 
into this now.  My primary interest is having a build script that 
selects the correct c++ compiler and get around a long-standing 
distutils bug.

I'm running into a little speed bump here.  It's failing on the 
pkg-config detection of gtk.  I have user-locally built and installed 
packages for gtk (and many other things), so I set my PKG_CONFIG_PATH to 
a custom location.  However, it appears that scons isn't passing this 
along to 'pkg-config'.  By poking into scons.Action._subproc, it looks 
like it is only passing a limited set of environment variables ("PATH", 
"LD_LIBRARY_PATH" and "HOME") to the pkg-config subprocess.  Is there an 
scons way to get it to use this environment variable?

If you think it is a problem in numscons, you can also try executing the 
scons
command with --log-level option for more detailed output of what numscons is
doing, for example --log-level=0; the lowest the level is, the more detailed
the output it.
