Building system again

| checking for GHC version date... darcs: getFdStatus: invalid argument
| (Bad file descriptor)

This happens to me on Windows (you don't say which platform you are on), and its always because I'm getting the Windows/System32 sort, instead of the Unix sort.  I fix it by putting msys in my path before Windows.

The error message is v confusing.  And my error message isn't the same as yours, so it might not be the same problem.  However the "GHC version date" thing seems to invoke a number of commands, and if any of them get the "wrong" one, thing will probably fail strangely.
