Installation question: cpphs, unix, and HEAD

[Malcolm Wallace]

This line:

>> cabal: cannot configure unix-2.4.0.1. It requires base ==4.2.*

seems not to square up with the installed database:

>> >~/ghc-head/bin/ghc-pkg list
>> /Users/kfisher/ghc-head/lib/ghc-6.13.20100831/package.conf.d:
>>    base-4.3.0.0
>>    ...
>>    unix-2.4.0.1

which suggests that the HEAD's libraries are misconfigured.  The unix  
package has an explicit dependency on base-4.2.*, yet no base-4.2.* is  
installed (only base-4.3.*).  Probably the HEAD's unix.cabal file  
needs to bump the permissible dependencies up a bit.
