[R-SIG-Mac] rgl

[Simon Urbanek]

Benilton,

you're compiling for Tiger on Leopard with Leopard X11 settings.  
Unfortunately rgl includes --R_opts from libpng which won't work when  
targeting Tiger. So you have two options:

1) fix rgl, e.g. by using:
sed 's:--ldflags:--libs:' configure > 1 && mv 1 configure && chmod a+x  
configure

(really correct solution is also to add --L_opts, but in our case  
that's taken care of by X11 already)

2) target Leopard instead of Tiger (default for R-devel, but requires  
tweaking for R 2.6.x)

Since you are building 64-bit, I wonder why you are using R-2.6 as  
that is doesn't have Quartz support in 64-bit, unlike R-devel.

Cheers,
Simon

CC to Duncan: to avoid the above it may be a good idea to use --L_opts  
and --libs only on Darwin, because rpath-like behavior is the default  
linker behavior anyway.
