Yet Another pkg-config program, this time as a perl script.
Not all flags and options are implemented yet, but it works well enough
to build a bunch of ports and xenocara (which requires pkg-config).
It is not yet activated in the build; I'm committing to allow for in-tree
development (including a man page).
ok espie, matthieu
