Solved, the problem was that rserve_client in the pack subfolder of swish was missing the library. I gave the command swish$ make packs but it was not rebuilding the pack of swish

Seems something is messed up in your installation. Works fine here and on the public swish (which runs a recently built version). It is a bit hard to see what as I don't know what you build how and on which system. See whether you can really find the file. Use (Linux) ldd to see whether the .so file dependencies can be found, etc.
