I had the exact same problem, so I:
rm ~/.grassrc5
source /etc/csh.cshrc /etc/csh.login
and it worked just fine.

-------------------------------------------------------------------------Subject: grass5pre4 tcltk error under OS X
Platform: other
grass obtained from: Trento Italy site
grass binary for platform: Downloaded precompiled Binaries
GRASS Version: 5.0pre4when calling tcltk from within grass5, the following error message appears:
GRASS 5.0.0pre4 > Error in startup script: can't read "env(TCLTKGRASSBASE)": no such variable
while executing
"source $env(TCLTKGRASSBASE)/main/menu.tcl
"
(file "/usr/local/grass5/bin/tcltkgrass" line 22)[1] Exit 1 tcltkgrass
This error did not exist with grass5pre2, but begun yet with grass5pre3. I encountered a similar bug report (#913) in the list, but it was not really resolved, as the user did not respond to a request of further information.
I am looking forward for any advice,
many thanks,
