5047,ghc fails to build if HOME is not seth,nomeata,igloo,"Hi,

some Debian build daemons do not set $HOME, to ensure that package builds do not modify that. ghc 7.0.2 fails to build in that case:

Here is an example build log: https://buildd.debian.org/fetch.cgi?pkg=ghc&arch=powerpc&ver=7.0.2-5&stamp=1300976974&file=log&as=raw ending with
{{{

ghc-cabal: HOME: does not exist
make[2]: *** [libraries/Cabal/dist-boot/package-data.mk] Error 1
}}}

The bug might be in the cabal-install code.
