OK. I CAN duplicate this weird problem. Only with the autogui startup.  
It gives a dbmi protocol error

db.select table=archsites database=/Users/Shared/grassdata/ 
Spearfish60_test/PERMANENT/dbf/ driver=dbf
Bad file descriptor: dup r
dbmi: Protocol error
Unable to start driver <dbf>

This command doesn't via tcltk, though it does work from the terminal.

If you start up tcltk via g.gui tcltk&, it works fine.

Anyone out there -- What happens in startup AFTER the TclTk gui is  
launched that might make db.select work with the following?

start up GRASS in TclTk GUI mode
db.select does NOT work (error above)
quit Tcltk
g.gui tcltk&
db.select DOES work
