r - Error in loading rgl package with Mac OS X

Question

I am trying to install rgl package (0.92.858) for R (2.14.2) under Mac OS X (Lion 10.7.3). When I try to load it (library(rgl)), I get the following error:

  Error : .onLoad failed in loadNamespace() for 'rgl', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl/libs/x86_64/aglrgl.so':
  dlopen(/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl/libs/x86_64/aglrgl.so, 6): Symbol not found: __ZN3gui13OSXGUIFactory12hasEventLoopEv
  Referenced from: /Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl/libs/x86_64/aglrgl.so
  Expected in: dynamic lookup

I have a Mac with Norwegian keyboard. Maybe this has something to do with the issue? However, I get the same error, even though I change the language to U.S. Has anyone experienced similar problem? Any way solving it?

Answer 1

I was having this problem with rgl 0.93.996 on OSX 10.9.2, but then after reinstalling several times I saw "Installing rgl - error: X11 not found but required, configure aborted"

A quick search took me here https://stat.ethz.ch/pipermail/r-sig-mac/2012-March/009077.html

Then I was finally able to get it to work by downloading XQuartz https://www.xquartz.org So it was X11 that was the problem in my case.
