If I recall correctly, you cannot use the dlopen() family
of functions from within a statically linked program under
Solaris. Since GTK+ relies on these functions for module 
loading, you probably will not be able compile GTK+ programs
statically on Solaris.

(The module loading is actually not mandatory - you may
 be able to disable the detection on Solaris by configuring
 GLib as:

  G_MODULE_IMPL=0 ./configure

 I haven't actually tried this though)

However, before giving up, it's possible, that you're just
missing some necessary libraries. You check that you
are including all libraries listed in the output
of gtk-config --libs.
