Note: existing binaries of this port will no longer run
on FreeBSD 4.2 or -current. They will report "user signal 2"
and abort due to a change in the pthreads library.
You will need to recompile/reinstall this port.
In theory this is not needed. This port does not need bison.
One of its dependent ports (openh323) needs bison and openh323
already has USE_BISON in its makefile.
However, without this bento complains that the port needs
bison and fails to build the package.
This is a H323 Gatekeeper for H323 compliant videophone programs
such as voxilla, OhPhone and OpenPhone (see /usr/ports/net/openh323)
and commericial programs like NetMeeting.
