I can vouch for (1) being correct since I am managing an HPC Cluster for a company right now. The way to to is modules.sf.net (or the newer and nicer Lmod which is Lua).
The usual need is for a multitude of versions being avaible and easily usable. This starts at the compiler level and goes up to stuff like I have 5 versions of Tool X. This needs Python 2.7.3 (yes exactly that version). Now make it easy for me to use it.
It has been my only touching point with TCL so far -- I. Don't. Like. It.
