I installed new version of gr_modtool script and it won't work. The error
is following:
[savi_ne@ts-070046nl gr-test]$ gr_modtool.py add -N rx_tx_message -t hier
-l python
Using Python < 2.7 possibly buggy. Ahem. Please send all complaints to

Here is the corresponding Cheetah code.

Any suggestions how to ovecome this except using older version which worked
perfectly?
