Here is some example output, which is a problem with the default version
of GS in FC2:

DEBUG: no psname was provided.
DEBUG: no psname was provided.
plot(1:10)

However, despite the msgs, the PNG file _is_ created with the plot.
I have noted the above problems when opening postscript files using gv,
where the above DEBUG msg appears in a pop up window. You have to clear
the pop up to get the file to display. This has been a problem since
moving to FC2.
Note that I installed the updated '-29' rpms from fedora development and
re-ran the sequence of statements _during the same R session_ and the
second sequence below is the result, with the DEBUG msgs gone:
> bitmap("test.png")
> plot(1:10)

This should not have been reported however to R-bugs, since as you note
above, it is not a bug in R. An FYI "heads up" msg to r-devel and/or
r-help would have been entirely reasonable though.
