#39491: moreutils conflicts with parallel
---------------------+--------------------------------
 Reporter:  david@…  |      Owner:  macports-tickets@…
     Type:  request  |     Status:  new
 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.1.3
 Keywords:           |       Port:  moreutils
---------------------+--------------------------------
 The "parallel" port installs GNU parallel. "moreutils" also installs a
 utility called "parallel", but it is incompatible with (and less
 flexible than) GNU parallel. I want to be able to install GNU parallel
 at the same time as the other utilities from moreutils (like "ts").

 Here's how other OSs solve this conflict:

 * Fedora doesn't provide the "parallel" utility at all in the moreutils
   package (I, personally, would be happy with this choice).

 * Ubuntu (and maybe Debian as well?) disables the "parallel" utility
   from moreutils if you install GNU parallel when moreutils is already
   installed (I would also be happy with this; does macports allow doing
   this?).

 Another option would be to add a "-parallel" variant to the "moreutils"
 port, and mark it so that it doesn't conflict with the "parallel" port.
 Is it possible to mark only a particular variant of a port as
 conflicting?

 Prior tickets: Ticket #30972 asked for this conflict to be resolved, but
 instead the two ports were explicitly marked as conflicting.
