Ah. Thank you. I had assumed that it connected to a server.
(Maybe my assumption was not entirely unfounded, given that the
installation instructions for lambdabot blithely state that you "just
cabal install lambdabot", nowhere suggesting that you might need to
*manually* install some of its dependencies.)

First I needed to 'cabal install hoogle'. Having done that, I needed
to do what you suggested:
> hoogle data
Which works swimmingly on Ubuntu, but fails on OS X, because wget
seems to be hard-wired. I seem to recall that at least one of the
packages that I installed over the last 2 days, automatically selected
wget on Ubuntu, and curl on OS X.
Any pointers to the least painful way of getting 'hoogle data' to work
on OS X?
Once I have the hoogle command line version working, it seems that
lambdabot truncates its output to just the first 3 lines. Is this
normal? Is there a way of customizing or changing this behaviour?
