The solution we use to exactly this problem involves one alias and one
source'd script, but I still think it works quite well. The alias is:

  alias setup 'set setup=(\!*);source /usr/local/lib/setup.csh'

This line is put in each user's .cshrc or in a common file sourced by .cshrc.
The script referred to in the alias follows my signature. A user
wanting to use TeX puts the command "setup tex" in his .login  or
gives it interactively.

The system administrator puts in more "if ($setup[1] == whatever) then"
statements in the setup file when new software packages arrive,  and
we thus have a unified approach to selecting environment variables.
