How to depend on a variant (or do I want subports)?

[Jeremy Lavergne]

> MacPorts doesn't let you declare a dependency on a variant of a port. It's issue #126. If the +server variant of net-snmp installs libraries, and other ports might want to use those libraries, then the +server variant of net-snmp should probably be turned into a net-snmp-server subport. net-snmp appears to be maintained by me :) but I don't really know much about it, so I wasn't aware that the +server variant installed any libraries. Can you think of any reason why we shouldn't delete the +server variant and just make the port install those parts always?
