This error is most likely caused by libtool (a big flaw in the way
libtool works if you ask me). This happens if you install library A
(glib in this case) and then link library B against it, then install a
new version of library A in a different location. The la-file(s) of
library B has the path to the old version of library A hardcoded.
The problem you describe happens then you link something against both A
and B (and the newer version of A is needed) since the la-file(s) of
library B forces linking to the old version of library A.

If this is the source of your problem, the solution is to fix the
la-files. Personally I just delete every la-file since the are not
really needed for linking (at least not on any platform I use). But
that might be a bit to drastic. Try looking up all la-files of all
libraries that GTK depends on and remove references to old libraries
you don't want to link against.
