X11 error while plotting in R on OSX

I can't reproduce your error in R 2.14.1 on an OSX 10.6.8 box. However, your example doesn't start with a graphics device specification. Did you start the graphics device with x11() before your first plot() command? If by "R on a terminal" you mean in Terminal.app, then you wouldn't normally get an X11() window:
plot( c(.1,.3,.4), ylim=c(0,1)) dev.list()

Did you start R, for example, in an xterm shell within an X windows
context?
If so, you could try starting the graphics device with x11(type='Xlib')
to see if it behaves better.
Finally, why are you using MacPorts? The binary download for CRAN should
work fine.
You should ask your question on r-sig-mac, although you might not get much
support for problems with the MacPorts version of R. I don't know.
