I just installed matlab version 6.1.0.450 (R12.1) and have a similar
problem to Shiro. I don't get any warning about /dev/ptmx, but I DO
get the following in /var/log/messages, and I am also unable to quit
(like Shiro). Other than these symptoms, matlab seems to work fine.

I am running FreeBSD 4.3-Release.
First... is anyone else able to successfully quit matlab?
