<p>I am wondering if I am missing something? it seems I am going around in circles! I install one complete stack on a Centos machine every week but getting past this in RHEl seems to be a challenge. Any pointers on what I should be looking for? (BTW I can't find the remi-test repo mentioned at the bottom of the message)</p>
