Text.ParserCombinators.Parsec requires -package text.

[Simon Peyton-Jones]

It's documented behaviour.

* import Text.ParserCombinators.Parsec will work without any -package
flags, if any installed package has a module
Text.ParserCombinators.Parsec.  It's very tiresome adding -package flags
all the time.

* The link step needs -package flags, because it only gets .o files, and
we didn't want it to start hunting through .hi files (though that would
be possible)

* ghc Main.hs is by definition equivalent to ghc -c Main.hs; ghc Main.o,
and the latter step needs the package flag. If you say ghc --make
Main.hs you'll get what you want.
