simple script to pull together a very small (<500k) tar file that builds
*just* libpq ... its not perfect, as it pulls in more files then is
necessarily required to build, but as it is, it requires one simple patch
to configure.in in order to work ...

Tested on FreeBSD ... patch for configure.in hasn't been applied, but
putting the script in place so that it doesn't get lost ...
