Thanks guys. Really appreciate the help. Will try ~amd64 for mplayer.<br>

<br>on the compression method normally used in gif. They let gif format<br>graphics become rather a standard, and then started demanding royalties<br>for the compression patent. Of course, royalties aren't something very
<br>compatible with open source, so that didn't work too well.<br><br>There were two responses among both the open source community and the web<br>community (which used both gif and jpeg). One was to develop an<br>uncompromised standard, the PING graphic standard, and switch to using it
<br>on most web pages and the like. (This was complicated by the fact that<br>MSIE didn't properly support PING for a long time.)<br><br>The other, as we have here, was to work with a library that used the same<br>standard but without the compression. Apparently, it was possible to read
<br>compressed gifs without violating the patent, but it wasn't possible to<br>create or do graphics work in the format, at least not and compress it.<br>Thus, libungif was born, using the workaround to decompress gifs, but when
<br>used to work with gifs, it would store them uncompressed.<br><br>The patents apparently expired between 2001 and late 2003, depending on<br>the location, so gifs can now use the normal compression without issue,<br>and there's little use for libungif any longer.
<br><br>According to a discussion some weeks/months ago on gentoo-dev, Gentoo is<br>deprecating libungif, and will eventually remove it from the tree.<br>Apparently, new versions of everything that could depend on either is now
<br>set to depend on libgif only. After a suitable length of time, or when<br>it becomes difficult to support libungif any longer (I don't believe<br>there's anything being done with it upstream any longer), it will be<br>
removed from the tree.<br><br>So... no new ebuilds should depend on libungif. If they do, it's a bug<br>and probably should be filed as such.<br><br>Meanwhile, existing ebuilds, particularly as currently merged, may still
<br>depend on libungif. However, most of them should work just fine if<br>rebuilt against libgif. Unmerge libungif (and remove that symlink you<br>created) so there's no libungif on the system. Then ensure you have a<br>
current libgif merged and do a revdep-rebuild -p to see what is detected<br>as needing remerged. Then go ahead and do the remerge of those packages,<br>either by running the command without the -p, or by emerging the<br>individual packages by name.
<br><br>Nothing should need to pull in libungif. It's still possible that some<br>old stable packages might want it. However, sticking those in<br>package.keyword with ~amd64 should result in a newer package that merges
<br>fine without libungif. If it's still required, then it's time to file a<br>bug (check first, of course, to see if there's already been one filed on<br>it).<br><br>--<br>Duncan - List replies preferred. No HTML msgs.
