</div>The cabal file lists zlib as a dependency:<br>
<br>
extra-libraries: z<br>
<br>
however, what 'z' means varies from distro to distro. Ultimately, your<br>
package manager has to solve this.<br>

</font></blockquote></div><br>Thanks for the reply, but I see two problems with this<br><br>1. cabal-install depends on zlib, so the .cabal file is not a help in this case.<br><br>2. Even if I did know that cabal-install was the usual package manager (saw one person today on Haskell Cafe that didn't) and thought to look in the .cabal file, then "extra-libraries: z" still wouldn't have helped me, as a human, know to install zlibc, zlib1g and zlib1g-dev.<br>
<br>3) one for luck, Debian doesn't have a package for cabal-install or the haskell zlib library, so it can't solve this for me either. Unless it can use .cabal files, and why would I know this and what would the commands be?<br>
<br>I had to completely remove Cabal and GHC and then spend 2 days resolving dependencies to get it working with the latest versions on OSX Tiger as well, so it's not as if this is a one off problem, unless I'm the problem. Therefore I think some human readable text on Hackage would be helpful.<br>
