 Hello.  I have this port:


 $ port deps rdp-projects
 Full Name: rdp-projects @0_6
 Fetch Dependencies:   subversion
 Library Dependencies: ffmpeg, gocr, ImageMagick, mplayer-edl

 If I run, for instance,

 $ sudo port mdmg -f rdp-projects

 it happily builds and works, and creates a dmg file.  So far so good.

 If I then re-run that same command, this is what I then get:

 $ sudo port mdmg -f rdp-projects
 --->  Computing dependencies for rdp-projects
 --->  Creating pkg for rdp-projects-0
 --->  Package for rdp-projects-0 is up-to-date
 ...
 Error: Requested variants "+gpl2" do not match original selection "".
 Please use the same variants again, perform 'port clean ffmpeg' or specify
 the force option (-f).
 Error: org.macports.mpkg for port rdp-projects returned: Processing of
 port ffmpeg failed
 Please see the log file for port rdp-projects for details:
     /opt/rdp_project_local/var/macports/logs
 /_Users_rogerdpack_dev_mplayer-
 svn_mplayer_patches_port_dir_multimedia_rdp-projects/rdp-projects/main.log
 To report a bug, follow the instructions in the guide:
     http://guide.macports.org/#project.tickets
 Error: Processing of port rdp-projects failed

 (as a note, specifying -f for force apparently does nothing to help here)

 $ port clean ffmpeg does "temporarily" overcome the problem, so that it
 works again once, but then some other dependency will fail in like manner,
 like perl5.  So if I then run a "port clean perl" and try it again, ffmpeg
 now fails again, since it's "unclean" from the previous run.  So I have to
 manually, one after another figure out all the dependencies, and clean
 them all (or clean all installed) first.

 Anyway appears this has been seen before:
 https://lists.macosforge.org/pipermail/macports-
 users/2009-December/018201.html though I didn't see a resolution.

 Anyway, see if you can reproduce it.
 Thanks!
