Ah.  I see.  Well, first off, I recommend uninstalling giflib and making
it a symbolic link to libungif.  Libungif is backwards compatible with
libgif and is more bugfixed in every sense.  Second, I suggest this
patch in addition to the last one I submitted.  I see now that in the
case where both libgif and libungif are installed, libgif is taking
precedence and causing problems with the new demux code.  Thus, this
patch will make configure prefer libungif over libgif.  Configure
originally looked for libgif first because of the compression code it
has, but now that I am aware of compatibility issues, compatibility is
more important than compression.  (By the way, after June 2003 LZW is no
longer patent protected.)

Yes, it helps very much.
