In general, you can find an answer via hayoo:

    http://holumbus.fh-wedel.de/hayoo/hayoo.html

e.g typing in "Text.Regex" brings:

    http://holumbus.fh-wedel.de/hayoo/hayoo.html?query=Text.Regex

says, for the first hit:

    regex-compat    
    Text.Regex. splitRegex  :: Regex -> String -> [ String ]

so yes, you need regex-compat
