Dear Roger Koenker, I have had just the same problem (rgl.snapshot returns "failed") on my Fedora Core 6 system.
It took me quite a while to figure out the solution, so I would like to post it here to make others' lives easier. My configuration: Linux zachariasz.dns6.org 2.6.18-1.2869.fc6 #1 SMP Wed Dec 20 14:51:19 EST 2006 i686 athlon i386 GNU/Linux Fedora Core 6 R version 2.4.0 Patched (2006-11-03 r39789) Package: rgl Version: 0.70 Date: 2007-01-06 What I had to do: Download the rgl package, install libX11, libX11-devel, libXt, libXt-devel, and then run: -------------------------- R CMD INSTALL --configure-args='--x-includes=/usr/include/X11 --x-libraries=/usr/lib' path_to_rgl_0.70.tar.gz -------------------------- The problem is that the ./configure script in the rgl_0.70 package does not seem to be able to locate the relevant X include and library paths. These have to be given explicitely, as shown. Hope this will help some in a similar situation.
