What bundles there are

There are plenty of "non-basic" GHC bundles. The files for them are called `ghc-x.xx-<bundle>-<platform>.tar.gz', where the `<platform>' is as above, and `<bundle>' is one of these:

`prof':

Profiling with cost-centres. You probably want this.

`conc':

Concurrent Haskell features. You may want this.

`par':

Parallel Haskell features (sits on top of PVM). You'll want this if you're into that kind of thing.

`gran':

The "GranSim" parallel-Haskell simulator (hmm... mainly for implementors).

`ticky':

"Ticky-ticky" profiling; very detailed information about "what happened when I ran this program" -- really for implementors.

`prof-conc':

Cost-centre profiling for Concurrent Haskell.

`prof-ticky':

Ticky-ticky profiling for Concurrent Haskell.

One likely scenario is that you will grab three binary bundles -- basic, profiling, and concurrent.
