I asked the administrators of the cluster I am using to install a PSI4 version with LibXC support. However, the problem is that we could not find any official instructions for the latest PSI4 release on how to do the installation to activate LibXC support (http://www.psicode.org/psi4manual/1.1/build_planning.html#faq-coredepend) and it is not listed under add-on dependencies either. Therefore, we were wondering whether the latest PSI4 release actually allows LibXC support. We found out that on the github repository, there are some files related to LibXC. However, the administrators specifically mentioned that the version they need to install has to be either a release or a release candidate, they will not install the master branch of a github repository. Therefore, my question is, how can one install Psi4 with LibXC support using the official release 1.1?
