+dnl The 8.x series postgres tarballs installs with a default prefix of

+dnl If the libpq.so file is in a non standard path, (one which the linker
+dnl doesn't search) then we must set the PG_LDFLAGS to -R/usr/wherever/
+dnl However, if the system happens to have more than one version of other
+dnl dependent libraries (eg. libgtk) in different standard paths. (eg:
+dnl /usr and /usr/local) then the wrong one may get linked. 
+
+dnl To overcome this, we first check for libpq in the standard places, and
+dnl only set PG_LDFLAGS if it's not found.
