thinking of the whole issue another idea came to my mind:
my not set up once (for a given system/platform) a bin directory (probably
somewhere under the pkgsrc tree) which contains symlinks to the desired
tools for the respective installation (if there should be any non-standard
tools to be used instead of the ones found in the standard path),
and include that directory in the path after the ./tools/bin, ./buildlink/bin
etc. directories but before the standard shell path? That way these tools,
if any such links would have been created, would take priority over the
repsective system tools but still would be overriden, if applicable, by
the GNU versions, for example.
