[R-SIG-Mac] problem with rgl

[Byron Ellis]

Ah. I take it you're using a pre-built version of RGL? Its looking for 
libpng in /usr/local/lib rather than /usr/local/png_1.2.5 so you're 
probably better off rebuilding RGL yourself (or descending into symlink 
hell). I don't use RGL personally so I don't know what building it 
would entail---I would guess Developer Tools + X11 SDK+libpng+libjpg at 
the very minimum.
