[R-SIG-Mac] rgl dependency?

[Timothy Bates]

Is there a dependency of rgl (required to run rCmdr with 3-D plots) that I
am unaware of?

This is the error R throws when trying to load the rgl package (downloaded
most recent from CRAN)


Error in dyn.load(x, as.logical(local), as.logical(now)) :
    unable to load shared library
'/Library/Frameworks/R.framework/Resources/library/rgl/libs/rgl.so':
  dlopen(/Library/Frameworks/R.framework/Resources/library/rgl/libs/rgl.so,

Error in .C(symbol.C("rgl_quit"), success = FALSE, PACKAGE = "rgl") :
