Ok, we'll probably have to hand-hold the build a little.  Automatic
bootstrapping has rotted slightly, but it should still be possible to
get a working compiler.

Yes, don't worry about ghc-pkg for the moment.  The first step is to
build the libraries (libraries/base, libraries/haskell98, and most of
hslibs).  Then build the compiler; at that stage you should have a
working compiler binary and it's all downhill from there...

This is very strange - just to be clear, what version of the GHC sources
did you start with?  There seems to be a version mismatch somewhere -
HsStd.h doesn't exist now (last seen in 5.02.X), and SET_HDR_ has an
extra argument in 5.04.  It looks like you generated your .hc files from
the 5.02.x sources, and are building them in a 5.04 or later source tree
- that's *not* a good idea, trust me :-)

Your experiences will be useful to us too, when we get around to
cleaning up the bootstrapping process.
