------------------------------------+---------------------------------------
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:

 {{{

 Any ideas?
