[LON-CAPA-admin] Update difficulties

[H. K. Ng]

Hi,

I have the same problem on the development server. I tried to follow
Stuart's instructions but is not successful. I cannot get to reinstall
LONCAPA-prerequisites (step (c)). I must not have disable epel properly.
Any suggestion how to fix the problem?

Thanks,
-hk
