Sorry, but i didnt receive your mail..
And pkg-config probably is not best solution on bsd and macosx systems because
it does not guarante nothing.
The best (and common) solution is CFLAGS and LIBS env variables. :-)
Or this pkg-config will allow custom paths for those C librares that do not
depend on pkg-config at concrete systems?
