From dbbec50a86f2c2ef08f1ccdb6dd040b530a5cf2a Mon Sep 17 00:00:00 2001
From: jlam <jlam@pkgsrc.org>
Date: Wed, 4 Feb 2004 00:11:07 +0000
Subject: Try to be smarter about detecting whether a cc in the PATH is
 actually GCC.  If it's found under ${LOCALBASE}, then assume that it came
 from a package and proactively require at least that version of GCC so that
 the correct package dependencies are added.
