No shared, just static then... ?? Still, don't know why the configure
script is failing here. I can't imagine that the library isn't being
found, so the only other thing that I've seen to be a consistent problem
with these library checks is missing dependencies to other libraries for
the configure code compile check (can your say alliteration ;). Anyway,
it's just a matter of finding out the minimal set of other libraries
needing to be referenced in order to compile a trivial piece of code
that will successfully link to libtk.
char * TkMainWindow();
int main (void)
$ $(CC) trivial_code.c -L/usr/X11R6/lib -lXt -ltk8.0 -ltcl8.0
Try compiling that, optionally adding -lSM -lX11 -lICE. If adding one
of these options makes it work where it didn't work before, I think I
know how to fix this problem (add $(X_PRE_LIBS) to ld_flags...).

ld != ldd. Confused? ld is the linker (puts the object files together
and resolves library dependencies during compilation). ldd is a program
to show shared library dependencies. Static libraries don't have
dependency info (external references are unresolved) so it doesn't work
