I've taken the easiest solution, that is... to remove the package from
the system.
This is named firebird1.5-common, and depends on gnugk and
libfbclient1. 

After that, I tried to install gnugk and see.., but it depends on
firebird and that library. I checked what was gnugk: gnu gatekeeper, a
pack related with the H.323 protocol and the IP telephony. I suppose
this is the the why firebird ended up in my system, though I can do
without it prefectly. 
Well, this is a laptop and is always suitable keeping the amount of
installed packages at bay. :-P

Thank you
