Since you bring up this point: any chance of getting Mac binaries from CRAN
again? Rgl is a particularly nice tool because of its portability, and
requiring users to install Xcode and Xquartz first makes life a lot harder for
non-technical users.
This is compounded by the fact that the automatic configuration is easily
broken. I have been unable to install rgl from source for some time on
Mavericks, and have now discovered that this was due to a HomeBrew-installed
imake in /usr/local.
Perhaps it would make sense always to use the well-known standard XQuartz paths
on Mac and only consider other locations if explicitly asked for by the user?
If rgl is using non-standard features in its makefiles, let me know what
they are. I use GNU make, so it's easy for GNUisms to slip into it.
We already have special handling for X11 on the Mac. I don't know why
yours isn't working, but it's pretty well-known that homebrew breaks the
usual R build system, so I'd blame it on that. If you are using
homebrew, you should be prepared to manually configure rgl. Or you can
send me a patch to rgl's configure.ac that works around the differences,
and I'll try it out.
