Various errors on Mac OS X

Hi,

I have just installed ghc 6.4.2 on OS X 10.4.6.  It was built from  
source using
ghc 6.4 as a bootstrap compiler.  (The build was done using  
darwinports.  Everything
was identical to the darwinports build of 6.4.1 except that --disable- 
openal and
--disable-alut had to be specified.)

I have successfully rebuilt haddock and the NewBinary library.  When  
building
the Crypto library (version 3.0.3), I get odd and not consistently  
reproducible
errors.

The ./Setup configure phase runs fine, but the ./Setup build phase  
fails.  Having
run this a few times, I've seen shell return values of 1(once), 11  
(once) and 10 (several times),
but no other error message.  Once I did obtain:

crossroads-able> sudo ./Setup build
Preprocessing library Crypto-3.0.3...

    Please report this as a compiler bug.  See:
    http://www.haskell.org/ghc/reportabug



I'll file a bug report, but are there any ideas on this one?

Best Wishes,
