Comment(by timthelion):

 After working with mcstar on IRC for a few hours(He was able to confirm
 the bug.  He is also using 7.4.2). He found the following work around for
 building programs with this package:


 {{{
 [timothy at timothy implicitCAD]$ cat implicitTest.hsimport Graphics.Implicit

 main = do
  writeSTL 1 "foo.stl" $ rect3R 0 (0,0,0) (0,0,0)
  return ()
 }}}
 {{{
 [timothy at timothy implicitCAD]$ ghc implicitTest.hs Linking implicitTest
 ...
