Russ asked to to help you.

The "can not run test program while cross compiling" error message means
that the configure script couldn't compile a simple piece of code (so
it figures that it must be compiling for another system).  The reason
for the compilation failure will be in the file "config.log" in the
directory where you executed the configure script.

Would you please send me that file.
