[afshin2003]

same problem here! I appreciate if it could be resolved :)

[mhrdev]

I think the problem occurs when echo command is not interpreting backslash escapes (could be bash version/setting issue).
Adding -e to echo command in tasks/lib.rb solved the problem for me:

Same error, mhrdev's fix worked for me. Centos (specifically Amazon's default EC2 AMI).

Same error and same fix also for me on AWS Linux instance

+1 for mhrdev's fix, CentOS 6.4.

[dalgibbard]

Another +1 for mhrdev's fix! CentOS6.4 x86_64 with default Python2.6;
I also needed to install ed and texinfo which I didn't see listed as a dep on the homepage :(
