Comment (by jeremyhu@…):

 Replying to [comment:53 egall@…]:
 > Actually I just came up with another idea: would throwing something like
 the following into perl5's universal variant work?

 > This is with including the `active_variants 1.1` port group somewhere
 earlier in the portfile of course. Also I'm adding the dependency on
 libstdcxx because I'm assuming that `require_active_variants` only works
 with ports that are already in a port's dependency list.

 No.  perl doesn't even use the libstdcxx port, so it should not be a
 dependency.
