I got this too, on windows. On linux I got a similiar issue, but I think the message was different. I ran the ghc stage2  with valgrind and it complained about there being an invalid instruction. I wonder if it is a 64bit thing. Anyone been able to build the LLVM backend with a 64 bit machine?

Hokay, so I've installed LLVM 2.7,
gotten ghc-HEAD-2009-10-23-ghc-
corelibs.tar.bz2, run ./darcs-all pull -a,
run ./boot, applied
add-new-llvm-code-generator-to-ghc_.dpatch
ghc-llvmbackend-20100328.dpatch
and written  the following in mk/build.mk:

GhcWithLlvmCodeGen = YES
GhcEnableTablesNextToCode = NO
SRC_HC_OPTS        = -H64m -O0 -fasm
GhcStage1HcOpts    = -O -fasm
GhcStage2HcOpts    = -O0 -fasm
GhcLibHcOpts       = -O -fasm
SplitObjs          = NO
HADDOCK_DOCS       = NO

And when I run make,

make -r --no-print-directory -f ghc.mk all
