Was glib originally built on 1.6 (i.e., with pth)?  If so, it and its
dependencies needs a rebuild.  (Generally, you cannot use dependencies built
for an older OS release, because they can have serious compile or link time
differences.)

If glib was built with 2.0, was it particularly old?  If so, this may
indicate that BUILDLINK_DEPENDS.glib needs a bump due to ABI breakage.

IGNORE_RECOMMENDED is useful for people who watch their rebuilds very
carefully; it is not very good as a general-purpose hammer.  If you use it,
you need to be mindful of possible ABI changes, including those from the
underlying OS.  (Perhaps this should be part of the loud yelling that pkgsrc
does at the end of a build if IGNORE_RECOMMENDED is set.)
