build failure

I've followed the instructions for building on the host for an unregistered x86_64 build, but when I do: cd glafp-utils/ & make boot && make I get: <...> ls/Outputable.lhs utils/Panic.lhs utils/Pretty.lhs utils/PrimPacked.lhs utils/StringBuffer.lhs utils/UnicodeUtil.lhs utils/UniqFM.lhs utils/UniqSet.lhs utils/Util.lhs ghc-6.4.20050224: Can't find codeGen/ClosureInfo.lhs-boot (imported from absCSyn/AbsCSyn.lhs) <> make[2]: *** [depend] Error 1 make[1]: *** [boot] Error 1 make[1]: Leaving directory `/u/kmacy/src/ghc-6.2.2/ghc' make: *** [build] Error 1 [1] + Done cd glafp-utils/
