Dear Martin,

This is a bug in the Makefile.am of rsplib. It should also install the CSP
files. I will fix this.

This is strange. When I compile this on my system (Ubuntu 8.10, AMD64) after
commenting out CSP stuff and inclusion of petestserver.h, linking works.
Could
you provide me some details of your Debian system (e.g. CPU, version, version
of gcc, etc.)? Could you also provide me your full sources and your Makefile?

rsp_info is used for passing configuration options to rsplib, e.g. registrar
addresses or CSP identifier.
