Controlling $PATH of build?

Hello all, just getting my feeds wet in writing Ports... Here is a tricky question: Postgres has it's own infrastructure for add-ons, see: http://www.postgresql.org/docs/8.2/static/xfunc-c.html This system relies on: /opt/local/lib/postgresql82/bin/pg_config Unfortunately, it's not in the $PATH, when the Makefile is called. I tried patching the Makefile, but the error seems to come from Postgres itself. Long question short: How do I control the $PATH exposed to the Makefile? It's the last puzzle to having a PL/Java port. Thanks, Hagen -- Dissertations are a successful walk through a minefield -- summarizing them is not. - Roy Fielding
