# revdep-rebuild -i
No ERRORS!

Fix:
# equery d glib
rebuild all (But in this case only =x11-libs/pango-1.29.4)

revdep-rebuild doesn't check for missing symbols, as there would be too many false positives.

By the way can the command
Code:
emerge @preserved-rebuild
solve the issue as well?

So is there really no better thing to do than:
Code:
emerge -av1 $(equery -q d glib | sed s/^/=/)

and rebuild 101 packages!???

or, some smart grep for g_mutex_lock in /usr/lib64 and pipe that through equery b...?

You could also upgrade dev-libs/glib back to the version which provides that symbol. Why did you downgrade it after installing packages that depended on it?
