Could you try rerunning configure, just to be sure?  Workaround.hs is
autogenerated by the configure script, so if you ran configure with a
different version of ghc installed, this file may be incorrect.

I'm not sure (since I don't have ghc 6.2.1, and my memory is iffy), but I
seem to recall that this openFd workaround was written before ghc 6.4 was
released.
