#52368: gpgme @1.7 allow installing with gnupg21

 Reporter:  leonardo.schenkel@…  |      Owner:  macports-tickets@…
     Type:  enhancement          |     Status:  new
 Priority:  Normal               |  Milestone:
Component:  ports                |    Version:  2.3.4
 Keywords:                       |       Port:  gpgme
---------------------------------+--------------------------------
 The current port has a dependency on `gnupg2`, which prevents it from
 being used with `gnupg21` even though that is supported by `gpgme`. I have
 attached a diff that changes the dependency to the `gpg2` binary instead,
 so either `gnupg2` or `gnupg21` will satisfy it. `gpg2` was left as the
 default dependency in case `gpg2` is not available.

 Patch is attached.
