Ooops. hit the button too soon. I have tried as arguments variation
of the fonts and family arguments to postscript, such as getting the
case right (i.e., lucida rather than Lucida). Alas
> postscript(file="test.ps", fonts="lucida");
*** glibc detected *** free(): invalid pointer: 0x0000000000f7dfb8 ***
this is under R 2.1.1, 2005-06-20, built under gentoo from scratch.
so, the problem is probably now internal, not the commands. I guess I
will now investigate glibc in a little more detail...

Thanks to Brian Ripley for pointing out that that should be ...
postscript(file="test.ps", fonts="lucida");
