Error when trying to connect to redshift db

After installing pgcli using brew, I get the following error when I try to connect to a redshift DB:

Traceback (most recent call last):

Any idea what might be causing this?

This is now available in v1.0. Please upgrade.

pip install -U pgcli

@amjith There are something to do with redshift? support or a new CLI for that? RedShift is being each time more usefull, we migrate some PG do RedShift here in my enviroment.
