I've just bought a new iMac with 10.5.4 of OS X. I installed R
2.7.1 on it with no problems.
I tried to install Xcode 3.0, but three downloads (two Firefox, one
Safari) were corrupt, so I installed 3.1.
Now, the weirdness:
When I try to install rgl from the CRAN source, or from a local
directory using R CMD INSTALL, the configure script fails with these
messages:
checking for X... libraries /usr/X11/lib, headers /usr/X11/include
checking for glEnd in -lGL... no
configure: error: missing required library GL
ERROR: configuration failed for package 'rgl'
** Removing '/Library/Frameworks/R.framework/Resources/library/rgl'
** Restoring previous '/Library/Frameworks/R.framework/Resources/
library/rgl'
However, if I run the configure script (as ./configure) within the
local directory, it succeeds:
checking for X... libraries /usr/X11/lib, headers /usr/X11/include
checking for glEnd in -lGL... yes
I can then move the configure script out of the way and R CMD
INSTALL proceeds (until it gets to the FTVectoriser error, which I'm
working on fixing).
Why would R CMD INSTALL make the configure script fail???
Hard to tell unless you look at config.log... Anyway, unless you work
around the bug in Leopard's X11 in your configure you have fix to X11,
GL is broken:

Also if you want to use X11 on Leopard seriously, it is recommended to
use this update:
