[R-SIG-Mac] Special characters not plotted

Hello,

I have a problem with the plotting of special characters that just occurred recently.
For example when I use the following code:

plot(1,1)
mtext(expression(phi))

Instead of the special character I get a black square. This actually happens for all special characters in a plot.
Any idea why this occurs? May be even related to fonts on my Mac?

The error is the same on 32-bit...

Thanks for your help in advance!
