Twilio SMS Alerting - Error: Module six was already imported

[dariusz_kwasny]

Hello,
I've configured alert with "Twilio SMS Alerts" action. The alerts are triggered but there are some twilio errors and SMS messages are not sent. The error message is:

ERROR sendmodalert - action=twilio STDERR -  /opt/splunk/etc/apps/twilio_alert/bin/pytz-2015.4-py2.7.egg/pytz/__init__.py:29: UserWarning: Module six was already imported from /opt/splunk/lib/python2.7/site-packages/six.pyc, but /opt/splunk/etc/apps/twilio_alert/bin/six-1.9.0-py2.7.egg is being added to sys.path

and final error message:

ERROR sendmodalert - action=twilio - Execution of alert action script failed

Does anybody have an idea how could I resolve this issue?
