To show the version:

$ bbcmd bbtest-net --version

/usr/lib/hobbit/server/etc/hobbitserver.cfg
bbtest-net version 4.2.3
SSL library : OpenSSL 0.9.8e-rhel5 01 Jul 2008
LDAP library: OpenLDAP 20343

Try running the gdb again against the bbtest-net binary at
/usr/local/hobbit/server/bin/bbtest-net on your system.
