The error comes from using QuickCheck 2, which happens to
also use the

(1) Add "< 2" after "QuickCheck" in the Wired.cabal file.
(2) Add "hiding ((><))" after "import Test.QuickCheck" in
Data/Hardware/Internal.hs
Emil,
my suggestion is: Please use alternative (2), at least if
there are no further problems with quickcheck 2! Otherwise,
depending on quickcheck
<2 just introduces unnecessary package incompatibilities.
Note that if you import hiding something that doesn't existing you'll
have a problem. Therefore this fix will require >= 2 for quickcheck, and
introduce incompatibilities either way.
That's why I like to import infix operators explicitly instead of hiding
some identifiers:
