Error message if not built

[matthieugomez]

Can there be a better error message if Arpack is not build? Something like "try ]build Arpack"

For now it gives something like error compiling napud.... Reason:image not found.
Googling the error returns this issue #5, which is incomprehensible for mere mortals.

Which version of Arpack are you using. I'd think that this is no longer a problem in 0.4.

Oh awesome! The error happened yesterday so it was on a previous version of Arpack.
