libgeda-config --version gesym-config --version which gnetlist ldd `which gnetlist`The first two should return the version of the installed tools (libgeda and the symbol library) and the next command should return the path to the gnetlist binary. The final command (only on Unix-like operating systems which include the ldd utility for listing dynamic dependencies of executable files or shared objects) will return which libraries are linked to gnetlist; all of the request libraries must be found for gnetlist to run. If these commands do not return the expected results, then most likely the gEDA tools are not installed properly. Please see the appropriate INSTALL docs (which came with the distribution) for more info on installing the gEDA tools.
