Nothing special:

checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
Canonicalised to: i386-unknown-linux
checking for path to top of build tree... 
/home/ashley/Projects/Collected/Haskell/ghc
checking for ghc... /usr/bin/ghc
checking version of ghc... 6.4
checking for nhc... no
checking for nhc98... no
checking for hbc... no

GHC             = /usr/bin/ghc
GhcDir          = $(dir $(GHC))
GhcVersion      = 6.4
GhcMajVersion   = 6
GhcMinVersion   = 4
GhcPatchLevel   = 0

# Canonicalised ghc version number, used for easy (integer) version
# comparisons.  We must expand $(GhcMinVersion) to two digits by
# adding a leading zero if necessary:
ifneq "$(findstring $(GhcMinVersion), 0 1 2 3 4 5 6 7 8 9)" ""
GhcCanonVersion = $(GhcMajVersion)0$(GhcMinVersion)
else
GhcCanonVersion = $(GhcMajVersion)$(GhcMinVersion)
endif

I think the problem is that I called autoconf etc. before I called 
darcs-all get, but not after. Calling autoreconf fixed the problem.
