Comment(by michaelld@…):

 In my testing, this issue happens only when one of MP's postgresql ports
 is installed, but -not- selected, and then qt4-mac is installed with one
 of the +psql variants.  In this case, the "pg_config" application found is
 that installed by ML.  This issue won't happen when one of MP's postgresql
 ports is selected, since "${prefix}/bin/pg_config" will be in the path
 before the ML version (in /usr/bin).

 I can fix this by specifying the exact version of "pg_config" to use for
 the correct variant. But, it'll be highly dependent on where "pg_config"
 is installed by the port, which right now seems to be
 "${prefix}/lib/postgresqlXY/bin/pg_config", where "X" and "Y" are the
 major and minor postgresql version numbers.  I'd rather not go this route
 (semi-hard-coding a path into the configure script), but I cannot think of
 a better way to do this since there's no guarantee that the user has had
 port select a postgresql version.  Thoughts?  Suggestions?
