 I'd like to use my Alex-generated lexer in my test-suite. I've tried
 adding other-modules/build-tools to my test-suite section, but upon
 building the Lexer module isn't found.

 I've got no problems using the lexer within my normal executable. Should I
 be able to use my Lexer in the test-suite?

 I'll attach a fairly minimal example, the Main module and the TestSuite
 module both use the Lexer, Main will compile, TestSuite won't:

 $ cabal configure --enable-tests
 $ cabal build
 [... blurb]
 Preprocessing test suite 'tests' for test-suite-with-alex-0.0...

     Could not find module `MyLexer'
     Perhaps you meant Lexer (needs flag -package ghc-7.4.1)
     Use -v to see a list of the files searched for.
