Thanks, Philipp. Worked for me as well. For others with the same symptoms, here&#39;s the incantation I used:<br><br><blockquote style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">

sudo cabal install --reinstall --force-reinstalls --enable-documentation --global  random-1.0.1.1<br></blockquote><br>And similarly for all of the other pre-installed packages. I reversed the order listed by &#39;ghc-pkg check&#39; in the hopes that the inter-package doc links would work out.<br>
