[R] compile errors with rgl-0.70.570 on FreeBSD

[Rainer Hurling]

Thank you for your work on rgl.

Reading in another thread about your new (inofficial) version of rgl 
(see below) I tried it with R version 2.5.0 alpha (2007-03-31 r40986) 
under FreeBSD 7.0-CURRENT. Unfortunately I got the following error:

-------
#R CMD INSTALL rgl_0.70.570.tar.gz
* Installing to library '/usr/local/lib/R/library'
* Installing *source* package 'rgl' ...

ERROR: configuration failed for package 'rgl'
** Removing '/usr/local/lib/R/library/rgl'
** Restoring previous '/usr/local/lib/R/library/rgl'

This version is not able to find any GL files on my system.

I did not have any problems compiling rgl_0.70.564.tar.gz.

If I can test anything please let me know.
