See my ports minivmac and pdftk for workarounds to make this easier  
for the user. I only select the default_variants if no conflicting  
variants have been selected.



minivmac can emulate several early Mac models. If you don't specify  
otherwise, it emulates a Mac Plus.

pdftk can be compiled with any version of gcc. By default I want to  
use the latest, gcc42, but if the user is on a slow PowerPC Mac and  
already has an earlier gcc and doesn't want to spend a day upgrading,  
they can use another variant.
