apparently sometimes even though cabal can figure out the dependencies for a package you want, it gets confused (or something) when it needs to figure out the &quot;transitive&quot; dependencies (that which needs to be installed for the direct dependencies to also install). So  try doing a cabal install of that version of template  haskell with the explicit version  <div>

cabal install template-haskell-2.4.0.0<div>that should solve it<br><br><div class="gmail_quote">On Sun, Mar 21, 2010 at 7:57 PM, Bernie Pope <span dir="ltr">&lt;<a href="mailto:florbitous@gmail.com">florbitous@gmail.com</a>&gt;</span> wrote:<br>

&gt; Straight from Zurihac: I&#39;m very pleased to announce the 1.0.0 release of the Salvia web server.<br>
&gt;<br>
&gt; Salvia is a feature rich web server and web application framework that can be used to write dynamic websites in Haskell. From the lower level protocol code up to the high level application code, everything is written as a Salvia handler. This approach makes the framework extremely modular and extensible.<br>


&gt;<br>
</div><div class="im">&gt; To do a full install first run `cabal update&#39; followed by `cabal install salvia-demo&#39;. Now you can run the salvia-demo command and point your browser to <a href="http://localhost:8080/" target="_blank">http://localhost:8080/</a> .<br>

</div>Hi Sebastiaan,<br>
<br>
I was looking forward to a new version of Salvia.<br>
<br>
Do you have minumum requirements for GHC? I tried to &#39;cabal install<br>
salvia-demo&#39;, but with no luck:<br>
<br>
cabal install salvia-demo<br>
Resolving dependencies...<br>
cabal: cannot configure syb-with-class-0.6.1. It requires template-haskell<br>
==2.4.*<br>
For the dependency on template-haskell ==2.4.* there are these packages:<br>
template-haskell-2.4.0.0. However none of them are available.<br>
template-haskell-2.4.0.0 was excluded because template-haskell-2.3.0.1 was<br>
selected instead<br>
template-haskell-2.4.0.0 was excluded because ghc-6.10.4 requires<br>
template-haskell ==2.3.0.1<br>
<br>
Cheers,<br>
