Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

cabal: Error: some packages failed to install:
aeson-0.6.1.0 depends on vector-0.10.0.1 which failed to install.
snap-core-0.9.3.1 depends on vector-0.10.0.1 which failed to install.
vector-0.10.0.1 failed during the building phase. The exception was:
ExitFailure 1

what to do?

I can make account in my server, and give access for people who can help with my problem.
