Wow, it sure has taken me a long time to get back to this, but I got it to work!  Two ways actually.  I did them both from scratch, just to make sure I understood what was going on and could communicate it for the next poor sap that is as ignorant as I was.<div>
<br></div><div>All this is done with GHC-6.12.3, cabal, readline-1.0.1.0,</div>
<div><br></div><div>In both cases, readline needed to be install.  On a mac, this is troublesome because the mac comes with editline.  Macports installs readline fine, except you have to make sure it&#39;s universal (&#39;port install readline +universal&#39;) since GHC needs 32-bit libraries.  When installing the haskell readline package, cabal has to be told where to find the macports readline (&#39;cabal install --configuration-option=--with-readline-libraries=/opt/local/lib --configuration-option=--with-readline-includes=/opt/local/include --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include readline&#39;).</div>

<div><br></div><div>The two ways of installing lambdabot branch from here.  The first is from hackage, but it needs to be patched and I don&#39;t think the patch is complete anymore.  The patch is at <a href="http://www.haskell.org/haskellwiki/Image:Lambdabot.patch" target="_blank">http://www.haskell.org/haskellwiki/Image:Lambdabot.patch</a>.</div>

<div><br></div><div>cabal unpack lambdabot</div><div>cd lambdabot</div><div>wget &lt;patch url&gt; -O | patch -p1</div><div>cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include</div><div>
<br>
</div><div>lambdabot should compile, but will complain about arrows when run (because the patch is insufficient).  You can manually correct it, or try the other method: installing from darcs.</div><div><br>&#39;darcs get <a href="http://code.haskell.org/lambdabot" target="_blank">http://code.haskell.org/lambdabot</a>&#39;</div>

<div>(Note: you&#39;ll want mueval too: <a href="http://www.haskell.org/haskellwiki/Lambdabot/Building" target="_blank">http://www.haskell.org/haskellwiki/Lambdabot/Building</a>)</div><div>I had to manually install Stream-0.3 as lambdabot required &gt;= 0.3 but something else required Stream &lt; 0.4.  &#39;cabal install&#39; in the lambdabot dir and it should be happy.</div>

<div><br></div><div>Should/can I update the haskellwiki with this install process?  Should the mac readline info go there too?</div><div><br></div><div>Thank you to everyone who helped me sort this out; I learned quite a bit.</div>
