[R-SIG-Mac] problem with rgl

[simone gabbriellini]

well, R looks for the libpng12.0.dylib file in  /usr/local/lib/.
There it find an alias which points to the real folder.
I saw that that alias is broken (it doesn't point to anywhere), and  
maybe all my problem can be solved by repairing that alias.

Do you know how to make an alias via bash, cause I need superuser  
privilege to make changes in those folders?

I used rgl binary version, and Bill Northcott libpng package.

Cheers,
simone
