As I suggested in a previous message to the list, putting addon  
modules in GISBASE is actually the impractical part.

Especiallly on OSX, *adding* to an already installed application  
(.app package) is not recommended.  And a non-admin user will simply  
not be able to do that.

Fully controlling by the env var is probably a good idea, so it's  
like PATH and [DY]LD_LIBRARY_PATH. hmmm.  I'd have to figure out how  
to split strings in C to reduce it to one env var that works like the  
other env vars.


Any comments on the C itself?  I wasn't sure about memory allocation  
stuff, I'm not good with that.
