Running script from BBEdit/TextWrangler gives "tput: No value for $TERM and no -T specified"

If I write a script in BBEdit/TextWrangler, e.g. #!/usr/bin/env python print 1234 and choose "Run" from the #! menu, I get this in a new document: 1234 tput: No value for $TERM and no -T specified tput: No value for $TERM and no -T specified tput: No value for $TERM and no -T specified How do I get rid of those 3 extra lines?
