Require it to build - i.e., GLib now uses APIs from liblzma - or only require it to decompress the source tarball?  It 
looks as if GLib 2.28.8:

        http://ftp.gnome.org/pub/GNOME/sources/glib/2.28/

has both .xz-compressed and .bz2-compressed tarballs, whereas earlier releases had both .gz-compressed and 
.bz2-compressed tarballs.

If it's only needed to decompress .xz-compressed tarballs, we could use the .bz2-compressed tarballs, instead; Mac OS X 
does come with bzip2, so we wouldn't need to install anything.

On the other hand, xz seems to compress a lot tighter than bzip2:

        glib-2.29.92.tar.bz2     18-Sep-2011 16:38  7.2M
        glib-2.29.92.tar.xz      18-Sep-2011 16:38  5.4M

so if xz can be quickly downloaded and installed, that might save enough time on the subsequent downloads to make it 
worthwhile.
