Yes, but that is just as true of the raft of packages that Rcmdr has in
'Suggests'. I suggested to John, and still think, that 'Suggests: rgl' is
right. Rcmdr will work without it, but works better with it and so if you
are installing Rcmdr you would like to install rgl as well (but it fails
to install it would not be a major loss).
