It is the .pc files that are the problem actually.

libtool already contains most of the information that pkg-config wants, and
it is much smarter about looking for deplips along the library search path
without requiring the manual maintenance of *another* path for a tool that
doesn't know it's way around the library search path.

The right solution would be to make sure that the .la files include any
additional details required to provide the output that pkg-config users are
chasing, and to add a mode to the libtool script to extract and display it.

No pkg-config tool required.  No .pc files required.  No PKG_CONFIG_PATH
required. Much much easier to use and maintain for all involved... pity
about all the man years wasted on pkg-config :(
