That is a strange one. I think the only way this error can show up is if the
tclblend.so is loaded, but the JVM can't read the symbols for some reason.
First off, did you pass a --prefix=/somedir/whereit/should/go type of
directory name to the configure script? I have seen some problems that
may be the result of trying to use the default --prefix. Also, this might be
a silly question but you did compiled with gcc and not g++ right, if you
used a c++ compiler it might mangle the symbols in some funky way.

If you did pass a --prefix to configure, then what happens if you run "make test"
from the build dir where you built Tcl Blend? Do the test cases pass when run
in the build directory? If you can't get Tcl Blend running in the build directory
then it is likely that one of the shared libraries it needs does not appear on the
runtime path. This tends to be caused by changes to the JDK layout which seem
to show up with every new release. The configure script may not know how to
find a runtime library that is needed. You could try running "make shell" from the
Tcl Blend build dir and then run "ldd tclblend.so" to see if it prints any missing
shared library deps. Running "make shell" like that will set the LD_LIBRARY_PATH
to the runtime paths defined in the Makefile.

If you are able to identify a shared lib dir that needs to be added to the runtime
path or a shared library that needs to be linked to, then the way to fix it is in
the configure script. If that seems to scary just post a diff of the Makefile before
and after your changes and I will fixup the configure script. There are some
other things you could try if none of this works, but that should at least give
you something to try next. Also, see the recent posts on this list about gcc 4
not compiling Tcl Blend correctly.

I hope that helps
