19 Did you do what I and others have suggested, a revdep-rebuild? Note that
20 existing packages on your system may still be linked against the old
21 library. Once it's in their binaries...
22
23 revdep-rebuild (as with anything portage related, run it with the -p the
24 first time thru to see what it's going to do) is designed to scan your
25 existing binaries to see what they need, and your existing library path
26 (that ld uses to find the libs it needs) to see what's provided. Then it
27 makes a list of all the binaries (both executables, and libs that load
28 other libs) that have unfilled dependencies using the existing libraries,
29 traces down the packages they belong to, and remerges them (or with -p,
30 displays what it would merge), the intent being to recompile and relink
31 anything that's missing dependencies, either linking against new or
32 alternate versions of same, or pulling in the required dependencies to
33 merge as well.
34
35 Of course, this only works once that library has gone missing. If you run
36 revdep-rebuild with the library (or a symlink pointing to an alternate)
37 still there, it'll think everything is fine and not list the package
38 owning the library in question for remerge.
39
40 Decently updated packages that formerly linked against libungif should now
41 link against libgif without difficulty. However, with existing package on
42 the system linked against libungif, it's only to be expected that said
43 binaries would have issues. The easiest way to fix them is to run
44 revdep-rebuild. In fact, revdep-rebuild, along with emerge --newuse
45 --update --deep world, should be a regular part of the routine to keep a
46 well maintained and upto date system.
47
48 (Another part of the same routine should be emerge depclean, but be sure
49 the revdep-rebuild and emerge --newuse are completed first, and check the
50 output of a --pretend depclean for stuff you know you want to keep around,
51 before letting it do its thing. Then run revdep-rebuild again afterward,
52 just to be sure.)
53
54 These apply to some degree to everyone, but a bit less to slower moving
55 stable, than to faster moving ~arch. Since ~arch may merge three versions
56 for every version that goes stable, including beta and rc versions on
57 occasion, cruft tends to buildup rather faster than it will on a stable
58 system.
