 [Institute for Advanced Study][IAS].  We take advantage of the PUIAS
 Computational repository to obtain a git v1.8.x package since the base CentOS
 repositories only provide v1.7.1 which is not compatible with GitLab.
+Although the PUIAS offers an RPM to install the repo, it requires the
+other PUIAS repos as a dependency, so you'll have to add it manually.
 
-Install the PUIAS Computational repository rpm
+Create /etc/yum.repos.d/PUIAS_6_computational.repo and add the following lines:
 
-    sudo rpm -Uvh http://puias.math.ias.edu/data/puias/6/x86_64/os/Packages/springdale-computational-6-2.sdl6.10.noarch.rpmo
