@kotak31
Is sudo ./setup.sh completed without any errors?
Can you share tail of log as well for setup.sh run?

[vvbandeira]

@kotak31, did you had a chance to try the suggestion above? Are you still having the issue?

[rovinski]

Just an FYI - the error means that the libffi package is either not installed on your system or is not found during compilation. The setup script mentioned above should fix that, or you can install the package on your own.

Depending upon the distro you might need libffi-devel.
