Comment (by kencu):

 The issue seems to really be with {{{glib2}}}, which for some as-yet-
 unknown reason no longer provides the file
 {{{
 gio/gdesktopappinfo.h
 }}}
 whereas it does provide that file on other systems, and apparently used to
 provide it on 10.6 i386 but now does not.

 I don't know why that is happening, but I did notice that
 {{{glib2-devel}}} does provide that file on 10.6 i386, so {{{gtk3}}} can
 build through if {{{glib2-devel}}} is installed.

 As an update of glib2 to glib2-devel seems impending, it is possible that
 it might be most convenient to just do that rather than sort out why glib2
 is no longer providing the missing file.
