Come to think of it, shouldn't ghc include this, instead of everyone creating their own shell scripts by hand? I don't think so. This is usually done in the userland -- at least in GNU+Linux distributions. More to the point, various distribution methods already include such things (e.g. NixOS, Debian's alternatives system, MacPorts' "port select") plus there are various mechanisms for implementing this on an ad-hoc basis (GNU stow, environment modules, etc.). Downstream packages implementing their own versions of this except speicifically on an opt-in basis (e.g. configure option) tend to interfere with these and complicate inclusion into existing package systems.
