[R-SIG-Mac] invalid graphics state using dev.print

[Paul Roebuck]

I'm trying to determine what's changed from my customized
[defunct] Panther setup to the basic Tiger one I am using
now.

$ open /Applications/Utilities/X11.app
$ open /Applications/R.app

> capabilities("png") # TRUE
> x11()
> plot(rnorm(10), main="test")
> dev.copy(device=x11) # so far so good
> dev.print(device=png, file="test.png")
Error in dev.copy(device = function (filename = "Rplot%03d.png", width =
480,  :
	invalid graphics state

Get same result when using "quartz" device.

I'm sure my previous environment had /usr/local/lib/libpng
but I'm trying to keep this machine a little closer to
stock, attempting to use only what typical non-developer
useR  would have loaded. Is this missing libary causing
the problem?
