That seems better to me also.

I see that pkg-config just recently broke this. See:

https://bugs.freedesktop.org/show_bug.cgi?id=119

   * main.c (main): Use add_search_dirs for both the compile-time
   defined pc_path and the run-time defined PKG_CONFIG_PATH.

I'd suggest we complain (via https://bugs.freedesktop.org/). If someone
sets PKG_CONFIG_PATH then they shoujld not get default pc_path added to
it. Maybe we could add a ./configure option to disable this.

We could use ./configure --with-pc-path but that would break our
pkg-config for non-pkgsrc uses.
