Description of problem: Please add glossaries, emulateapj, and revtex4 to texlive-extension. Version-Release number of selected component (if applicable): texlive-extension-2012-1.el7
(Also, you don't need a main texlive-extension package - drop the %files line; and %defattr() is long dead and not needed).
So, initial work on getting glossaries in has started, but we still need to add datatool-base, supertabular, and xfor as deps (and whatever they may depend on). Holding off more work on that for now.
