They both install /usr/include/gif_lib.h. The giflib ebuild appears to be a copy of the libungif one, or something - it has the same homepage listed. Some ebuilds depend on giflib, some on libungif, and some on both of them! The webpage says libungif only creates uncompressed gif's to avoid the lzw patents, and is the successor of giflib. We should do something about the situation, at least to keep them from overwriting each other's files. Hope I haven't understood the situation incorrectly, I'm very tired right now...

The lzw patent expired in July, at least in the States. http://www.unisys.com/about__unisys/lzw. I don't know if this matters unless they're the same package.
Both packages are still claiming ownership of gif_lib.h though and are overwriting each other's file. Just had an update to imlib-1.9.14-r2 fail during econf, unable to find gif_lib.h. I had tried out enlightenment, then unmerged and depcleaned enlightenment which had installed libungif as a dep. Unmerging libungif cleaned out gif_lib.h, repaired by remerging giflib.
Seems as though this has been addressed with the gif use flag. If USE gif is set libungif installs gif_lib.h otherwise giflib installs it. Can this be closed?
can this be closed?
Shouldn't comment #3 be the other way around? If USE=gif, giflib installs the header. That's what I get on my system here. Anyway, your description means a system can still be broken if USE gif is set when emerging gifilbg and unset when emerging libungif, or the way around. Are these two libraries actually distinct from one another, if their header is the same anyway?

'gif' is a bad name fo this useflag. USE=gif should work just like USE=png or USE=tiff. Some ebuilds stumble over this (e.g. fbi: #78243) A local useflag called lzw (use patented(?) lzw compression) for both libgif and libungif would be neat, so these libs can sort out the issue themselves, without stomping on the gif useflag.
wine-20050111 is another example of a package depending on gif_lib.h. I don't have the file, although either giflib or libungif was installed according to portage. I believe one or the other removed once the file, so I got left with the file completely.

Since you have the gif useflag set, giflib should provide gif_lib.h. That's the way it's currently being done, even though it's braindamaged. Maybe you flipped the gif useflag between merging libungif and giflib? That would explain why the header is missing.
Dozens of bug reports on other packages because of this issue...
According to Gentoo Weekly Newsletter: March 21st, 2005 (http://www.gentoo.org/news/en/gwn/20050321-newsletter.xml) : [quote] giflib and ungiflib hell Chris White starts a discussion on the libgif / libungif packages since they provide similar features, but libungif is deprecated. This resolved to the removal of libungif from portage. [/quote]. This resolve the bug.
Chris any status update?
libgif now blocks libungif and pretty much every package has been fixed by now
