Re: [eclipsefp-develop] EclipseFP 2.6.3 on OS X Yosemite and LunaSR1, GHC 7.8.3

[JP M. <jpm...@gm...>]

The haskell-src-exts gotcha on happy is annoying a lot of people (-:, see
https://github.com/haskell-suite/haskell-src-exts/issues/14.

Mind that on MacOS, GUI applications do not have the same PATH as the
shell, so double check the PATH in Eclipse is really what you think it is.
