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?

Perhaps you should add the directory containing `pygtk-2.0.pc'

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.
