 Building `NaturalSort-0.2.1` with GHC 7.0.1 RC 1:

 {{{
 $ cabal install --build-summary=log.bs --build-log=log.bl
 Resolving dependencies...
 Warning: NaturalSort.cabal: This package requires Cabal version: >=1.6 &&
 <1.9
 cabal: Error: some packages failed to install:
 NaturalSort-0.2.1 failed during the configure step. The exception was:
 user error (The package requires Cabal library version -any && >=1.6 &&
 <1.9
 but no suitable version is installed.)
 $ cat log.bs
 cat: log.bs: No such file or directory
 $ cat log.bl
 $
 }}}

 I would like the build log to contain the error.

 I have
 {{{
 $ cabal --version
 cabal-install version 0.9.2
 using version 1.9.2 of the Cabal library
 }}}
 but this is not a released version; if nothing else, I have the #697 patch
 applied.
