[GRASS5] grass5 on darwin - problem w/init - SOLVED

[andy agena]

Hi Glynn:

adding the 'g' below did the trick and GRASS is functioning again!   
thanks for your help.

however, I still need to add 'TCLTKGRASSBASE: /sw/grass5/tcltkgrass' to  
my ~/.grassrc5 (which is no big deal, of course).

as for details on Darwin's linking, I couldn't find any good  
documentation Apple's site, but the Darwin developers' list might be a  
place to start <http://search.lists.apple.com/darwin-development>.

as I'm poking around GRASS, 'g.select.pg' isn't in the bin directory,  
and I'm assuming this is another error in my make.log file.  Can you  
see any reason why this module failed to build?


Thanks again.

Take care,
Andy
