Try running the external MathLink program directly from the shell's
command line.  If everything is ok, you should see a prompt that looks
like this:

	Create link:

If you are running into the problem that I am expecting, you will see an
error indicating a crash instead:

	segmentation fault

This happens when a program is linked against an older MathLink library
(libML.a) that was created under either libc 5 or glibc 2.0 and then
executed in an environment that runs glibc 2.1 or later.  The fix is to
get a newer release of the MathLink Developer's Kit for Linux, which is a
free download from the WRI Technical Support website.

A more detailed description of the problem may be found at this FAQ URL:

If you have updated your MathLink Developer's Kit already and are still
running into troubles, please contact Technical Support directly at
