Hi All, I've found the problem: for some reason, during installation (make install) mod_dingaling is not linked against libgnutls.so. As a test I have added the "-lgnutls" switch in src/mod/endpoints/mod_dingaling/mod_dingaling.la to gcc in the relink_command. After re-issuing "make install" everything works fine and I can connect to gtalk. I guess this can be classified as a "configure" error. Regards, Fede
