The problem here is name confusion. Unfortunately, the name cgi-compat
has nothing to do with the Network.CGI.Compat module. compat in the
former stands for "compatible with ghc < 6.6", or more precisely, with
base < 2.0 and network < 2.0. If you want the Network.CGI.Compat module,
install an older version of the cgi package, e.g.

There's no migration guide, only the haddock docs:
However, since the old API was so limited, you'll probably only need
'getInput', 'getVar', 'output', and 'runCGI'.
