I've recently moved to Fedora Core 6 and installed the latest R from
the tar.gz file as I've done for some years now.  The make check
returned no errors that I could see so it came as a surprise to see
this:

> plot(8)
Error in plot.new() : could not find function "X11"

It's possible that there's something different from previous versions
with the graphic card driver in this installation but I'm mystified
why there didn't seem to be any problem detected (or perhaps, more to
the point, reported) during the installation of R.

Everything else I've tried to do seems to work, but I don't do a lot
in R before there's a reason to draw plots, so I need to find out
what's going on.


Where do I need to look to work out what could have failed?

TIA
