Thanks both Brandon and Michael for your help. My bad. I wasn't aware of the small step to take after install Haskell Platform that Brandon pointed out. After done that, everything works just fine.

Hi all,

I'm trying to install Yesod as suggested by this page.


with the following command 

cabal update cabal install yesod-platform yesod-bin --max-backjumps=-1 --reorder-goals

But I constantly get the following error.

...

136 warnings and 6 errors generated.

Failed to install vector-0.10.9.1

cabal: Error: some packages failed to install:

aeson-0.6.2.1 depends on vector-0.10.9.1 which failed to install.

...

The error appears to be from the fact that cabal cannot install vector package.

Any suggestion to fix the problem. I'm on Maverick, Xcode5, Haskell Platform 2013.2.0.0 64bit

Thanks,
Ed
