Yikes. That is really odd. You might be running into some
goofy junk related to how the JVM loads shared libs and
how Tcl loads shared libs. For instance, you need to
load libtclblend.so in Tcl and in Java (with System.loadLibrary()),
but I do not know if that matters.

Is there any chance that tclexpat.so is linked to another
Tcl shared lib?
Try running:
% ldd tclexpat.so
and see if that says something about libtcl8.3g.so in the link dep line.

You might also want to try building tclexpat.so with stubs
support. That might work a little better.
