Shell worksheet error under Snow Leopard

[Daniel Lord]

Shell worksheets worked fine for me under Leopard but I just upgraded
to SL a few weeks ago and the first time I tried to use one, I get 39
lines of the following error text: tput: No value from $TERM and no -T
specified.

TERM is defined as mach-color in my .bashrc and I have a fancy color
bash prompt defined which works fine. So what shell is the worksheet
invoking that it cannot read the TERM environment variable for use
with tput?

I searched this list and didn't find a mention of this problem so
maybe it is unique to my insalltion (or few people use shell
worksheets ;-)
