Mathew:

I didn't include you email address because they are continually returned 
to me.

How much of ecl in /usr/local/lib is required to make executables run on 
another machine? Do I just copy libecl.so.11.1.1, or is 
/usr/local/lib/ecl-11.1.1 and its contents also required? Is it 
necessary to provide the links to libecl.so.11.1.1 also?

Thanks,
