 Installation of a cabal package under Windows Vista with UAC activated may
 fail even when working as administrator, because cabal doesn't request the
 necessary rights to write to, e.g., "c:\Program Files\Haskell\<whatever>".
 A workaround is to start an "Administrator console" to start Cabal from a
 process which already acquired admin privileges.

 Cabal should request the necessary rights instead of failing.

 cabal-install should check in advance whether the target destination is
 writeable and fail early or request the necessary rights. (currently,
 cabal-install fails after compiling all dependencies. After starting
 cabal-install again from an Administrator console, everything has to be
 build again).
