1. MFC from linux_base-fc6 (well, sort of -- an idea taken):
Add some directory trees since we still use fc4 infrastucture ports.
Inspirited by the wrong behaviour of "install file1 file2" when file2
should exist and be a directory...
2. Bump PORTREVISION.
3. Fix pkg-descr (FC6 -> FC7).
4. s/@dirrm/@dirrmtry for /compat/linux/proc.
