The MPW makefiles that come with 3.1g don't work if Mac Pict support is
enabled.  The simplest solution is to remove the following lines from
config.h:

#define GET_SYS_FILE_HANDLE() MacFile_GetFileHandle()
#define READ_SYS_IMAGE(i,n)  MacFile_ReadImage((i),(n))
#define SYS_DEF_EXT    ".pict"

and near the end

#define GET_SYS_FILE_HANDLE() MacFile_GetFileHandle()

To be honest (and very direct), compiling POV-Ray is not an easy task
for a beginner.  The source code is complex and not well commented, and
when you run into problems you should be able to resolve them on your
own.  If you don't know how, compiling the source code will most likely
be a very frustrating and discouraging experience.

There are more rewarding, smaller programs (like the Apple sample code)
out there that can get you started to learn programming and using MPW.
If you search a bit on Apples developer website, you will probably find
some good tutorial or other information that will be really helpful
getting started, too.
