You are right. When I try to install parsec by myself I get the same
error message.
But neither "ghc-pkg list" nor "ghc-pkg check" prints any error
messages. The latter only prints some warnings because of missing
haddock files.
Complete output of the error message:

Hi Antoras,
My suspicion is you've ended up with corrupted packages in your
package database - nothing to do with Hoogle. I suspect trying to
install parsec-3.1.2 directly would give the same error message. Can
you try ghc-pkg list, and at the bottom it will probably say something
like:
The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
warp-1.1.0
I often find ghc-pkg unregister<warp> --force on all the packages
cleans them up enough, but someone else may have a better suggestion.
Thanks, Neil

Hi Neil,
thanks for your effort. But it still does not work. The old errors
disappeared, but new ones occur.
Maybe I have not yet the most current versions:
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.4.1
$ cabal --version
cabal-install version 0.10.2
using version 1.10.1.0 of the Cabal library
This seems to be the most current version of Cabal. The command
'cabal info
cabal' brings: "Versions installed: 1.14.0" but not 1.15

Hi Antoras,
I've just released Hoogle 4.2.9, which allows Cabal 1.15, so hopefully
will install correctly for you.
Thanks, Neil

Hi Antoras,
The darcs version of Hoogle has had a more permissive dependency for a
few
weeks. Had I realised the dependency caused problems I'd have
released a
new
version immediately! As it stands, I'll release a new version in
about 4
hours. If you can't wait that long, try darcs get

Thanks, Neil

Ok, interesting info. But how to solve the problem now? Should I
contact
the author of Hoogle and ask him about how solving this?

I don't know where the dependency to array-0.3.0.3 comes from. Is it
possible to get more info from cabal than -v?
hoogle-4.2.8 has "Cabal>= 1.8&& < 1.13", this brings in Cabal-1.12.0.
Cabal-1.12.0 has "array>= 0.1&& < 0.4", this brings in array-0.3.0.3.
It is a mess to have 2nd instances of libraries that already come
with
GHC, unless you are an expert in knowing and avoiding the treacherous
consequences. See my
http://www.vex.net/~trebla/haskell/sicp.xhtml
It is possible to fish the output of "cabal install --dry-run -v3
hoogle"
for why array-0.3.0.3 is brought in. It really is fishing, since the
output
is copious and of low information density. Chinese idiom: needle in
ocean
(haystack is too easy). Example:
"selecting hoogle-4.2.8 (hackage) and discarding Cabal-1.1.6, 1.2.1,
1.2.2.0,
1.2.3.0, 1.2.4.0, 1.4.0.0, 1.4.0.1, 1.4.0.2, 1.6.0.1, 1.6.0.2,
1.6.0.3,
1.14.0, blaze-builder-0.1, case-insensitive-0.1,"
We see that selecting hoogle-4.2.8 causes ruling out Cabal 1.14.0
Similarly, the line for "selecting Cabal-1.12.0" mentions ruling out
array-0.4.0.0
