Comment (by ryandesign):

 Adding the makefile portgroup has made it use the right compiler, yes, but
 it's still not using -arch flags, and the build still fails on some
 builders possibly because of parallel build issues:

 https://build.macports.org/builders/ports-10.8_x86_64-builder/builds/41388/steps
 /install-port/logs/stdio

 Just adding the makefile portgroup is often not enough. Because each
 project's makefile is different, you have to compare the makefile to the
 way the portgroup works and maybe change some of the options the portgroup
 exposes or maybe even patch the makefile before it will behave correctly.

 Fortunately the build fails when using the newly-added universal variant,
 so fixing it doesn't require increasing the revision.

 You could disable parallel building or try to figure out in what way the
 makefile's dependency declarations are wrong and try to fix them.
