problem building HEAD out of the box.

[Ben Lippmeier]

Alright, on further investigation it turns out this problem was due to  
my /bin/sh being a link to the dash shell instead of bash.

The IT people here have recently upgraded our linux distro, and http://wiki.ubuntu.com/DashAsBinSh 
  says that from Ubuntu 6.10 they're using /bin/dash instead of /bin/ 
bash. The page says that dash is supposed to be Posix compliant, but I  
guess the GHC scripts aren't.

I didn't work out exactly what part of the GHC build tickles this bug,  
but I'll add a warning to the wiki page.

Thanks,
Ben.
