Hi, Steve.

Unfortunately, rgl is not a bioconductor package, so reporting here is not
likely to help much.  If you utilize the R help system and do:

help(package=rgl)

the maintainer's email is listed.  My guess is that that person will need at
least the output of sessionInfo() to begin to diagnose the problem.
