It didn't take that long for me (maybe a minute or two). A possibly useful observation in case anyone else takes a look at this before me: when I debugged it and ctrl-C'ed to interrupt every now and then, the interrupt always happened inside a call to XQueryColor (in bitgp(), in devX11.c), so that may be the slow part.

Re: [R] PNG Problem on Windows 98

On the other computers - the x-axis labels, the legend text and the mtext (on the bottom) is missing. Attached are simple example files one in jpg (which is ok) and one in png format. I don't have access to a Win98 machine to test any more. However, I notice that I've been doing builds with an out of date version of the PNG library (version 1.2.0). I've just downloaded 1.2.5, and am building r-devel with it. Could you download r-devel from CRAN tomorrow, and see if this bug is fixed? (I'll upload it today, but it won't be visible until tomorrow.) You should look in http://cran.r-project.org/bin/windows/base/rdevel.html to find the download. Make sure it is dated Feb 18 or later.
