problems compiling gtk3

[Josh Bialkowski <jbialk MIT EDU>]

Hello, I'm having some trouble compiling gtk3 on ubuntu lucid. I've
successfully compiled and installed the following versions of the
pre-reqs from source:

glib-2.28.3
pango-1.28.3
atk-1.33.6

When I try to build gtk+-3.0.3, configure finishes without any errors or
warnings, but when I "make" it get's caught while making the tests:

Making all in tests
make[4]: Entering directory `/home/josh/Codes/c/gtk/gtk

The problem seems to be with libio-2.0.so referencing some things so I
took a look at what that file was linked to

:~/Codes/c/gtk/gtk+-3.0.3$ ls -l /usr/local/lib/libgio*
-rwxr-xr-x 1 root root    1095 2011-03-15
14:17 /usr/local/lib/libgio-2.0.la
lrwxrwxrwx 1 root root      22 2011-03-15
14:17 /usr/local/lib/libgio-2.0.so -> libgio-2.0.so.0.2800.3
lrwxrwxrwx 1 root root      22 2011-03-15
14:17 /usr/local/lib/libgio-2.0.so.0 -> libgio-2.0.so.0.2800.3
-rwxr-xr-x 1 root root 4544706 2011-03-15
13:29 /usr/local/lib/libgio-2.0.so.0.2793.0
-rwxr-xr-x 1 root root 4476130 2011-03-15
14:17 /usr/local/lib/libgio-2.0.so.0.2800.3

and it looks like it's linked to the right thing (0.2800.3). Putting
some of the undefined symbols into google brings me to the docs for
glib.. but since the shared object file is a link the the shared object
that I just built, I'm not sure what the problem could be. Does anyone
recognize what the errors might be and what I could be doing wrong?

Thanks for any help.
