[R-SIG-Mac] GDD installation

[Simon Urbanek]

Richard,

before I go into details, do you have a specific reason for  
recompiling GDD yourself? It is available in binary form on CRAN, so  
all you have to do is to say install.packages("GDD") and it works out  
of the box (R 2.2.0).

This seems like a problem in the installation of your libgd. Make  
sure "gdlib-config" is on your PATH (i.e. when you type gdlib-config  
you get its help and no error). That script is generated by libgd and  
provides all compilation flags necessary to link against libgd.

It seems as if your libgd is missing JPEG and PNG support. Please  
make sure you libgd has both JPEG and PNG support. Freetype and  
fontconfig are useful, too (FT is included in the Apple X11).

As I was saying earlier, it works on Mac OS X and Mac users don't  
even have to worry about compiling it at all.

Cheers,
