fail on yum install (CRYPTO_num_locks)

[jonhornstein]

Just tried to install pcp on an AWS machine.

I went to the download page to get instructions and got the following error. Any idea which dependency has not been handled?

cheers

Maybe the default python link on this box has been replaced from the RHEL normal python2 one, and broke yum in general. This is not a pcp error.
