The .orig files can be made with the following process with a git archive:

# in git archive for package $PKG
mkdir ../$PKG-$VERSION
git archive master | tar -x -C ../$PKG-$VERSION
cd ..
tar -cf $PKG_$VERSION.orig.tar $PKG-$VERSION
gzip $PKG_$VERSION.orig.tar
cd $PKG-$VERSION
debuild
Making these packages can be a pain in the rear. The debian/rules makefiles for gcc and wpilib are not code snippets I'm particularly proud of... but they work.

Also, if you make a mistake and the build dies, debian wants to completely rebuild the whole package from a distclean. So don't mess up when you're compiling GCC... you wouldn't believe how much time I wasted only to learn that I forgot to pass -e WIND_BASE to debuild...
I did the same thing, luckily, the first thing I did was check the config.log!

Regardless, ironically, I've got this stuff running on my mac via a manual install much better than I do on debian with the packages, but I'd love to help with development, and I want to stay current so I'm trying to switch over. Right now, theres something broken where its not finding the C++ includes (i.e. #include <string> won't work, etc) and I have no idea why. If anybody has run in to this, I'd appreciate a tip. Debugging as you're reading.

Also, just as a thought, since your debian package for wpilib has a builddep for cmake, and AFAIK, just invokes it, why don't you just use CPack? Seems like that would be a little bit cleaner solution, but that's just me.

EDIT: Still having that issue with the packages. I'm going to try the packages you built and see if that makes a difference. Just to make sure, I've been installing them in this order:
Code:
binutils
wrs-headers
gcc
buildscripts
Any help is appreciated.
