Comment(by litoh):
The problem remains, here's what I did:
Installed new darcs to avoid sleeping:
$ darcs -v
> 2.5.1 (release)
I followed the GHC build guides at
http://hackage.haskell.org/trac/ghc/wiki/Building/Hacking (with --no-cache
option)
$ darcs get --lazy --no-cache http://darcs.haskell.org/ghc
$ ./darcs-all --testsuite get
in mk/build.mk:
BuidlFlavour = prof
$ perl boot
$ ./configure --with-ghc=/usr/local/bin/ghc-7.0.1.20110217
(I had to recompile for profiling support and define an older GHC build. I
used the current RC build)
$ make -j2
$ make install
$ ghc --version
> The Glorious Glasgow Haskell Compilation System, version 7.1.20110223
$ cabal install yampa
$ ghc --make Test.hs -o test -O2 -fforce-recomp
> test: <<loop>>
:/
