Were you having other problems?

Still?  Hmm, I just built the snapshot from this weekend, and  
everything works as expected (NVIZ/X11 OK, gis.m display OK).

The gcc line looks comparable to what I get.  The first warning about  
not prebinding makes me wonder - which version of GCC are you using?   
I think prebinding on on by default in GCC 3.3, and I've found that  
ported stuff generally in not configured for prebinding and fails.   
Probably nothing to do with the make errors causing problems itself,  
but GCC 3.3... that might cause multiple defs to be considered errors.

I suspect that, with Lorenzo's script, it's switching to GCC 3.3 to  
maintain Panther compatibility (tho that would have to happen with a  
sudo).  The other thing that might affect prebinding and other  
linking options is MACOSX_DEPLOYMENT_TARGET, which defaults to 10.1.   
I have mine set to 10.3 in my .bash_profile.


PS. very close to frameworks and a standalone universal GRASS app.  
^_^  Lorenzo - do you have any description on how to use your GRASS  
start app Xcode project or how it works?  Any updates to it? (it's  
over a year old)
