AFAIK, pkg-conifg quite sucks. If you use autotools, you should rely on libtool since the current pkg-config autotools support is quite unsatisfactory (especially regarding to other languages that C and cross compiling) . Writing and maintaining custom m4 macros is usually a nightmare, this is why pkg-config was created. That's how I see it, maybe I am wrong. Regards, Matej
