Hi Jacek,

The lambdabot hoogle command requires hoogle to be installed locally,
and to work.  Hence the first thing to ty is to run the hoogle command
line version, something like:

hoogle '[a] -> a'

If that doesn't work, maybe try building some hoogle databases.  One way to
do that is to run (on gentoo this needs to be run as root):

hoogle data

And if that works, to try it again:

hoogle '[a] -> a'

And if all that works hopefully it should work in lambdabot.  It
works in the gentoo-haskell overlay.

Regards, Mark
