change configure so that if postgresql isn't being installed as root,

do not configure in the perl5 interface.

the perl5 interface needs to be installed under /usr/local/lib/perl5/*, which
is generally owned by root.  This allows a non-root build/install with the
only root requirement being the make/install of hte perl5 stuff...
