This was solved by actually looking at the error and noting it didn't have
iqstream_max_calculator - the file stuff was fine. I then noted that the
appropriate .so files were in different asset locations. When I first:

  $ export
OCPI_LIBRARY_PATH=/home/bpadalino/projects/opencpi.git/projects/assets/artifacts:/home/bpadalino/projects/opencpi.git/projects/core/artifacts

I can now get the ocpitest assets to work correctly. This seems to be
another issue with symbolic links not being correctly created or propagated
through the project.

I'll take a deeper look and hopefully resolve the issue. Sorry for the
noise, but thanks for the quick responses.
