Comment (by kencu):

 works as I designed it to:

 {{{
 PortGroup           legacysupport 1.1

 legacysupport.newest_darwin_requires_legacy 18
 legacysupport.use_mp_libcxx yes
 }}}


 {{{
 $ port -v installed pdal
 The following ports are currently installed:

 I haven't tried any tests.

 Probably could be tweaked to link statically in some cases, etc, but I'll
 leave that as an exercise to the reader.
