Recently I have submitted some patches to libg3d's ml to fix some problems under cygwin. It is a little bit tricky to get a working libg3d installation but if all dependencies are fullfilled it is just the usual ./configure ... && make && make install procedure.

After some troubles, rc bug creation and a lot of help from Holger Levsen, it was possible to unblock libg3d for lenny. Lenny has currently 0.0.6-3 (by accident as some release manager said), but this will change in the next days - but the big endian fixes are in it too
