PROBLEM: Can't compile Gtk+-1.3.4

Sorry to ask such a silly question but I'm stuck again. After
successfully compiling Glib-1.3.4 and after finally successfully
compiling Pango-0.15 I can't configure Gtk+-1.3.4. When I use
"./configure" I get:

	*** that the run-time linker is not finding GLIB or finding the wrong

Why this error, Pango seems to find Glib? I used "ldconfig" but it
didn't help. Do I have to edit "/etc/ld.so.conf" first and if how? I'm
doing this on a Debian woody system i386. I copied all *.pc file from
Glib and Pango to the pkgconfig directory.
