In my case, they were checked -- using pkg-config against the wrong 
(incompatible and old) pkgconfig *pc files. Once I removed the old *pc 
files, my problem was fixed.

(Nevertheless, I still think pkg-config should have a easy way to 
override or modify the pkgconfig path used. Setting environment variable 
is not easy, since you don't know what the defaults are in the first place 
without grepping binary or running ktrace on it for example.)
