Ah, that's an interesting situation. The difference between those two pkg-
config is where they find their .pc files: one searches the 32-bit /usr/lib 
and the other the 64-bit one. You can use the 64-bit pkgconfig, but you need 
to make sure that every 32-bit devel package you have also has the 
corresponding 64-bit one so the .pc file will be found.

Hopefully the compiler options will be the same. The include dirs should be 
and pkg-config does not print the system libdir. Unless Ubuntu or Debian broke
