This comes from glitz removal (bug #330397), as soon as cairo-1.10 gets
stabilized, depclean will try to remove glitz, but removing glitz will
break a lot of apps, needing to rebuild them and, until then, having a
partially broken system.
I then thought on running revdep-rebuild --library libglitz-glx.so.1
BEFORE removing glitz (to prevent breakage), but later I remembered it
wouldn't work as rebuilt packages would link again against
libglitz-glx.so.1.
Then, my idea would the following:
Would be nice if I could tell portage to make compilation think
libglitz-glx.so.1 is not present in real system (maybe sandbox could
prevent its readability inside build environment), and then, I could run
"revdep-rebuild --library libglitz-glx.so.1" before removing glitz and
affected apps would not link to it, allowing me to safely remove glitz
later without having had a broken system at any time.
What do you think? Thanks

I think you want to update to portage-2.2 (you need to unmask it
manually). It does exactly what you want in this case.

I am not sure if portage-2.2 would also cover this case: in this
example, the problem appears because of people uninstalling
*intentionally* media-libs/glitz (as it's no longer needed)

Ideally, the build system(s) involved would have options to explicitly
disable linking against the deprecated library.
Barring that possibility, something like your sandbox idea seems like
the second-best solution.
On par with the the sandbox idea would be to migrate the deprecated
library to a directory which is not included in the default library
search path, and to use a global LD_LIBRARY_PATH setting so that your
apps can find it until they are rebuilt. Then you could execute your
rebuilds in an environment with a modified LD_LIBRARY_PATH value that
excludes the path of the deprecated library.

Didn't think about that last LD_LIBRARY_PATH option, looks easier for
now. Thanks
