Package: libglu1-mesa-dev Version: 7.4.1-1 Severity: minor It seems that the X11 libraries in unstable (7.4) have pkg-config integration that wasn't in the testing version (7.0). But I can *accidentally* upgrade only some libraries, and thus get a system that has .pc files that don't work.
Perhaps the 7.4 libraries should have Depends: ... (>= 7.4)? Here is a reproduction of the error I caused accidentally. $ aptitude search -F%p%v ~i~nlibgl.?1-mesa-dev libgl1-mesa-dev 7.0.3-7 libglu1-mesa-dev 7.0.3-7 $ pkg-config --cflags --libs glu Package glu was not found in the pkg-config search path.
