cabal install hangs installing yesod-platform

Question

The cabal install of yesod-platform hangs downloading xss-sanitize. NetHogs shows no network activity related to this download.

$ cabal install yesod-platform
Resolving dependencies...
Downloading xss-sanitize-0.3.4...

Other packages download and install without delay.

I'm on Fedora 18. The haskell-platform and cabal-install are up-to-date from the repos.

$ cabal --version
cabal-install version 0.14.0
using version 1.14.0 of the Cabal library

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.4.1

Edit

I left it run overnight it seemed to give up on xss-sanitizer, and continued installing the other dependencies. Here is the tail.

My companies internet filter was blocking the haskell-xss-sanitize package as a possible XSS threat. Specifically the test modules. Have your admin white-list hackage if possible.
