active_variants: allow multiple port names to be specified

[ryandesign (Ryan Carsten Schmidt)]

Currently, I can use e.g.:

require_active_variants pango x11

to require that the pango port be installed with the +x11 variant. However it should be permitted for users to use the pango-devel port instead. We need a way to tell require_active_variants of alternate port names. Perhaps this syntax should be supported:

require_active_variants {pango pango-devel} x11

Even nicer might be if we could just use normal dependency specifiers, e.g.:

require_active_variants path:lib/pkgconfig/pango.pc:pango x11

[cooljeanius (Eric Gallager)]

This would make sense considering you can already specify multiple variants with this. If you can specify multiple variants with require_active_variants, I would think it would be theoretically pretty easy to take the code for specifying multiple variants and turn it into code for specifying multiple ports.

Patches welcome, in this case :)

I think it might actually be easier to move this into base at this point, because base probably has an easy way to resolve path-style (and other) dependencies.

I posted about this issue on the ​mp-dev list. I've attached the patch here, too; it implements the "path:...:port" version, just like a dependency.

I've fixed the ports that were incorrectly limiting the dependencies to a single port due to the active_variants checks in

• r104850: gtk3
• r104851: gtk2
• r104852: py-cairo
• r104853: pango
• r104854: pango-devel
