net/coccinella: still usable?

Just came across this XMPP client with whiteboard functionality when
looking at audio/snack consumers due to daniel's py3 update on ports@.

coccinella had its last update 13 years ago, last comment on HOMEPAGE is
four years old.

It fails to play sounds, tries to open /dev/mixer (did we ever have that?)
and fails to connect via TLS:

$ coccinella
vidcap: warning: unable to acquire sapi default
ERROR: failed vidcap_sapi_acquire
IAXCLIENT: iaxc_initialize: cannot initialize video!

Unable to open mixer /dev/mixer

The connection error appears in a window:

preshook ::jlib::tls_parse failed: 1

while executing
"fileevent $sock readable"
(procedure "tls_proceed" line 39)

Perhaps SSL 3.0 or TLS 1.0 or plain text connections work?

Does anyone still use this?
