title: Error in loading rgl package with Mac OS X
body: <p>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:</p>
  
  <pre><code>  Error : .onLoad failed in loadNamespace() for 'rgl', details:
    call: dyn.load(file, DLLpath = DLLpath, ...)

  <p>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?</p>
