[R-SIG-Mac] RGL again

[stefano iacus]

One more thing.
R 2.1.1 that comes from CRAN has libR statically linked against  
libpng, thus png support is there already (try png(); example(plot);  
dev.off())
But if you want to build rgl package you need to have libpng include  
files (at least).
So you only need to install libpng following the steps at http:// 
www.economia.unimi.it/R and remove all *png*.dylib entries from /usr/ 
local/lib.
