HTTP package - supported GHC versions

If it is not too much of a hassle, rather support old versions of GHC. 
As mentioned below, there are long term support versions of Linux that 
package older GHCs.

I was positively surprised that the latest QuickCheck still supports GHC 
6.8.  Agda aims to support GHC 7.0 for a while still (which keeps me 
from using some nice syntax extensions to Haskell).

Cheers,
Andreas
