That would be my preference too. We've already addressed many of the reasons
why something would fail on an older system: we have newer cctools, ld64, clang
available in MacPorts. The one big remaining issue is that a lot of
Mac-specific software can only build with the latest SDK, so we need to add a
MacOSX.sdk port with subports to install each major version of the SDK. I
worked on such a port awhile back but didn't finish it:
https://github.com/ryandesign/macports-ports/blob/MacOSX.sdk/devel/MacOSX.sdk/Portfile
An alternative solution is to devise a method where certain ports can opt into
being built on a newer system. See https://trac.macports.org/ticket/60878 for
more on that proposal.
