</div>In order to test my proposed solution (see below), I tried building<br>
web-routes-quasi 0.3.0 from git, but I get another cabal version conflict<br>
failure:<br>

I assume this means that it needs ghc 6.12 (which I haven't installed<br>
yet). Do you really need template-haskell-2.4.*, or would 2.3.* suffice as<br>
well? In that case you could relax the version constraint.<br>
