Comment (by kencu):

 So I just installed a new installation of MacPorts on a virgin Leopard
 Intel system.

 Then I made the tiny change in
 <​https://trac.macports.org/wiki/LeopardSDKFixes> in
 AvailabilityInternal.h.

 There was a hangup at autoconf barfing on gtk-doc, so I installed autoconf
 2.6.9_5 instead of 2.7.1.

 But other than that, it installed all the way to clang-7.0 without
 touching the keyboard. Took a while, but it's all finished.

 I will have to manually upgrade libcxx to the +emulated_tls variant still
 to get full functionality, but other than that, it's clean.
