pdf font embedding --- again

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");
