Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively you may set the BASE_DEPENDENCIES_CFLAGS and  
BASE_DEPENDENCIES_LIBS environment variables
to avoid the need to call pkg-config.  See the pkg-config man page for
more details.
