tcltkgrass: yes or no

[grass user]

O.K., I must stop beating around the bush and get GRASS up and running on 
a SGI and SUN (Solaris2.3).  I have the compiled binaries from moon and also
the tcltkgrass source files from LAS on moon.  I would really like to get 
tcltkgrass going after seeing the demos at the User's Conference in Reston,
besides, I will have to move to tcltkgrass eventually.  But most importantly,
I need GRASS running soon, within a couple weeks if possible.

My question is this:  Should I get GRASS4.1 going first and worry about
tcltkgrass later, or can I just jump right into tcltkgrass with not too much\
extra effort?  Are there enough of you out there who have tcltkgrass experience
to help me get it going if I run into problems?  So I am asking for the 
wisdom of others who have already traveled this road:  Start with GRASS4.1, 
worry about tcltkgrass later, or start with tcltkgrass, it's not much more
difficult than GRASS4.1 itself?

Any discussion would be very much appreciated!
