The problem here is the .la files I think. Since GTK is linked to ATK
and pango, the .la files of ATK and pango are read by libtool. But
because you had the old version of glib then you installed ATK and/or
pango, the path to the old version of glib (/usr/lib) is contained in
these .la files.

I don't know the "right" solution to this problem. But you can edit the
.la files in question to point to the new location (/usr/local/lib), but
that can become quite cumbersome in the long run. What I personally do
is to delete all .la files, but since I know that is discouraged I will
not recommend it to anyone. (I have never understood the whole point of
the .la files, they only cause trouble, but they are probably good for
something.)
