It's not hard-coded. I'll test the Linux build of all this stuff when I get a chance, probably next week sometime.

These are the requirements as I recall them:

The PYTHONPATH environment variable needs to point to a directory containing both csnd.py and _csnd.so or _csnd.pyd (not sure what it is on Linux but it looks like it is .so). csnd.py dynamically loads _csnd.so. I would try the PYTHONPATH approach if the site-packages setup is not working.

_csnd.so is linked with libcsound64.so.5.1 by the compiler. This shared library needs to be configured for loading or be or in a directory pointed to by LD_LIBRARY_PATH. It's OK for there to be a soft link. I thought, however, that the real file was libcsound64.so.5.1 and the link was libcsound64.so.

Hope this helps, more later,
Mike
