gimp-gap-devel-2.7.0 fails on Snow Leopard

My system

Problem with MPlayer When I try to sudo port install gimp-gap-devel I first get an error saying MPlayer doesnt build on Snow Leopard

--->  Fetching MPlayer
Error: Target org.macports.fetch returned: MPlayer does not compile on Snow Leopard.  Please use multimedia/mplayer-devel instead
Error: The following dependencies failed to build: MPlayer
Error: Status 1 encountered during processing.

This I solve by changing dependency in the $(port dir gimp-gap-devel)/Portfile to mplayer-devel

Problem with libavcodec Next it fails to build using the libavcodecs included in the external ffmpeg library

--->  Building gimp-gap-devel
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_gimp-gap-devel/work/gimp-gap-devel-2.7.0" && /usr/bin/make -j2 all " returned error 2

Solved by appending --disable-libavformat to configure.args of the gimp-gap-devel Portfile ​changeset.

With these adjustments I am now able to build gimp-gap-devel on my system, and when i run gimp I recognize GAP has been integrated to a Video-tab. But functionality is severely crippled due to the changes made. It doesnt work.

Is this still a problem with the current version?

mplayer-devel was made the default runtime dependency in r70306.
