Panda Bullet

Ok, I started trying to write a SConscript.Linux file for this, and it mostly seems to be working, but it’s trying to include a file that doesn’t get installed by Bullet:

$ scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
g++ -o built/bullet_composite.os -c -fPIC -DFORCE_INLINING -DBUILDING_PANDABULLET -DHAVE_PYTHON -Ibuilt -Isource -I/usr/include/python2.7 -I/home/whitelynx/packages/panda3d-cvs/src/panda3d/built/include -I/usr/include/bullet/bullet source/bullet_composite.cxx
In file included from source/config_bullet.h:26:0,
                 from source/config_bullet.cxx:15,
                 from source/bullet_composite.cxx:1:

compilation terminated.
scons: *** [built/bullet_composite.os] Error 1
scons: building terminated because of errors.

I’m assuming this file is in the Bullet source… is this actually needed? Shouldn’t we be sticking to things that Bullet provides in the install?
