I've installed Matlab Release 12 under 4-Stable; it cannot find
/dev/ptmx and complains:

| MATLAB was unable to open the pseudo-tty master device /dev/ptmx.
| The unix() and ! commands will not work in this MATLAB session.  Other
| commands which depend upon unix() and ! will also fail.  Please check
| with your system administrator and confirm that this device exists with
| the proper permissions.

|                                 Sep 21 2000

This causes some difficulties and I haven't been able to find any
solutions or work arounds in the archives.  

This is on a recently updated machine:

| knock [rdmurphy]% uname -a
| FreeBSD knock.econ.vt.edu 4.3-STABLE FreeBSD 4.3-STABLE #0: 
|    Fri Jun  1 11:31:50 EDT 2001     
|    rdmurphy@knock.econ.vt.edu:/usr/obj/usr/src/sys/KNOCK  i386
| knock [rdmurphy]% pkg_info | grep linux_base
| linux_base-6.1      The base set of packages needed in Linux mode

Any suggestions?

Thanks-

RDM
