Hi Rick! I got the the same error day ago on my server. Probably it happens because you have two <i>network</i> packages in you system.<div><br><div>Try to compile all your packages  only on  network-2.2.1.10, and delete package network-2.3</div>

<div><br></div><div>Hope it helps you <br><br><div class="gmail_quote">2011/3/23 Rick Richardson <span dir="ltr">&lt;<a href="mailto:rick.richardson@gmail.com">rick.richardson@gmail.com</a>&gt;</span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

<div>I just installed the generic 7.0.2 binary on Ubuntu  on both 32 bit and 64 bit machines.  Then I rm&#39;d   .ghc and .cabal  then fetched the current haskell platform. Built and installed. </div><div><br></div><div>


After cabal installing all of the dependencies cabal said were required for yesod,  I run yesod.. the script creates the project.</div><div><br></div><div>When executing runhaskell devel-server.hs  I get this message</div>


<div><br></div><div><div>GHCi runtime linker: fatal error: I found a duplicate definition for symbol</div><div>   ghczm7zi0zi2_AsmCodeGen_zdfMonadCmmOptM2_closure</div><div>whilst processing object file</div><div>   /usr/local/lib/ghc-7.0.2/ghc-7.0.2/libHSghc-7.0.2.a</div>


<div>This could be caused by:</div><div>   * Loading two different object files which export the same symbol</div><div>   * Specifying the same object file twice on the GHCi command line</div><div>   * An incorrect `package.conf&#39; entry, causing some object to be</div>
