 Good. I'm marking this bug as solved.

 stderr was also recorded, I think.
 I don't know MacOS, but on Linux this would NOT redirect stderr to
 log.txt. Redirections are evaluated from left to right, so what you are
 saying here is: redirect current stderr to *current* stdout (which is the
 console!) and later you say redirect *current* stdout to a file. It's like
 assignmnets:
 {{{
 stderr = stdout;
 stdout = log.txt;
 }}}
 This doesn't mean that stderr is now log.txt - Bash is not a functional
 language :) So you need to say `>log.txt 2>&1`.

 Erik, I think something is very wrong with your build. I'd suggest that
 you try to pull a clean tree and build there. If that fails I'd mail ghc-
 devs or fill a bug report.
