There are a lot of variables in a GHC build, we'd have to be sure that those 
measurements were taken on completely identical builds - i.e. profiled libs 
built, same optimisation levels, via-C and same version of gcc (or -fasm), GMP 
library built/not built, etc.

If you think your build is slow, try building it on Windows sometime :-(
