Hi Tim,

I have solved the problem.  It seemed like the .so files were present and where they should be
but they were not being found.  To test this theory, I copied /usr/lib/libpigpio.so and
/usr/lib/libpigpiod_if2.so to the same folder as the Squeak VM.  After that everything worked
as expected.  I have asked Dave Lewis off line if there is a better way than copying the files.
I will post what I end up with when I'm sure what is best.

Thanks again.
