Likewise here the other way - that is, as long as I can remember it's  
always given the error, then gone into the mapset selection anyways.

Though there is another problem I DO have - if the location or mapset  
is invalid, I can't create a new location by values in the GUI -  
clicking Define new location with projection values button in the GUI  
gives me (the good db name is 'grassdb'):

access: No such file or directory
ERROR: LOCATION << /Users/kyngchaos/Documents/gis/grassdbz/ 
spearfish60 >>
        not available
     while executing

[previous error message repeated a few times]

"exec -- $env(GISBASE)/etc/grass-xterm-wrapper -name xterm-grass -e  
$env(GISBASE)/etc/grass-run.sh $env(GISBASE)/etc/set_data"
     invoked from within
".frame0.frameNMS.seventh.button invoke"
     ("uplevel" body line 1)
     invoked from within
"uplevel #0 [list $w invoke]"
     (procedure "tk::ButtonUp" line 22)
     invoked from within
"tk::ButtonUp .frame0.frameNMS.seventh.button"
     (command bound to event)


It doesn't even try to run grass-xterm-wrapper.  Even if I correct  
the DB location in the GUI, I get this error.  So it could be related  
to the problem you're having.  It works normally in the text startup.

How about my binary?  I recently added a 5/20 CVS build for download  
on my site.

Yeah, saw it, figured that's why you started on the error trapping.   
It sounded like they were using the old unix build, not a .app  
build.  The only difference is pre-init.sh - where the .app sets some  
GRASS env var defaults appropriate for the .app.

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
