The *safest* thing to do after pulling is to completely make clean, 
autoreconf, and build from scratch.  You may be able to avoid being that 
drastic if you know what you're doing.  There are quite a few 
dependencies in the GHC tree that aren't tracked explicitly, for 
practical reasons; for example, the build system doesn't know that when 
the .hi format changes you need to rebuild all your libraries.

I suspect something is out of date in your case, but I'm not sure what. 
    If you don't want to rebuild everything, you could try just 
rebuilding ghc/lib/compat, and then remove ghc/stage1/parser/Lexer.o, 
build stage 1, and then carry on with stage 2.
