Works fine for me ;)

Same here.

Hmmm, I made /usr/local/{src,bin,...} writeable by myself so I don't
need to be root when making things like mjpegtools - but that's just
my personal preference.

That list looks incomplete - it's not surprising there are undefined
symbols. The symbols that are missing are indeed in libglib2 but
-lglib2 is not given anywhere!
Here's what it should look like:

Notice that 'libgtk2' brings in libglib-2.0 (in addition to 'atk',
'pango' and so on)
(it says 1.9.0 because I'm working from the CVS version but 1.8.0
builds fine - it's only in the last couple days that any divergence
has begun to take place).

OK - then the question becomes "why does including gtk2 not bring
in the dependencies of libgtk2?". The answer to that might be in
the GTK2 .pc (pkg-config) file.
If you have the environment variable PKG_CONFIG_PATH set correctly
you should see this:
sms% pkg-config --libs gtk+-2.0
-L/usr/local/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm
-lpangoxft-1.0 -lpangox-1.0 -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -lglib-2.0
-lintl -liconv
See how gtk+-2.0 declares all the libraries it needs? If you do not
have output like the above then I would have to say that the GTK2
.pc file is incorrect

find the file gtk+-2.0.pc (I have it in /usr/local/lib/pkgconfig) and
take a look, the one I have is:
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
target=x11
gtk_binary_version=2.4.0
gtk_host=powerpc-apple-darwin7.7.0
Name: GTK+
Description: GIMP Tool Kit (${target} target)
Version: 2.4.14
Requires: gdk-${target}-2.0 atk
Libs: -L${libdir} -lgtk-${target}-2.0
Cflags: -I${includedir}/gtk-2.0
The 'Requires:' line will bring in the other libraries gdk-*, atk* and
so on.
> Can anyone provide advice on next step? Thanks.
Trace thru the pkgconfig files and make sure they're Require:ing all
the necessary files.
Good Luck!
