Comment (by tlockhart1976@…):

 Replying to [comment:5 mojca@…]:
 > There's another problem with this port. I'm listing it here, but if
 needed we could open a new ticket. The file `/opt/local/bin/sgmlspl` is
 used by all versions of perl, so `p5.16-sgmlspl` conflicts with
 `p5.18-sgmlspl` for example.
 Hmm. I'm trying to list conflicting variants but that does not seem to
 have an effect. I've added the lines:
 {{{
 variant p5.16-sgmlspm conflicts p5.18-sgmlspm p5.20-sgmlspm description {}
 {}
 variant p5.18-sgmlspm conflicts p5.16-sgmlspm p5.20-sgmlspm description {}
 {}
 variant p5.20-sgmlspm conflicts p5.16-sgmlspm p5.18-sgmlspm description {}
 {}
 }}}
 But it may not matter; the package does not seem to build for perl5.18
 anyway.
