Our default setup gives you a slow build for a few reasons: optimisation is set 
high, compiling via C is the default, GHC itself has to be built twice, and we 
ship a lot of extra libraries.

However, many of these things can be tweaked, and it has been reported that you 
can get a GHC build down to under 8 minutes on a dual-core, if you're prepared 
to sacrifice optimisation and extra libraries.  However, you can speed up the 
build a *lot* just by using the native code generator instead of compiling via 
C: gcc has been getting quite a bit slower recently.

Full details on how to tweak the GHC build are here:
