Unable to run the example clblasSgemmRandomBufferFuture.jl

Whenever I try to run clblasSgemmRandomBufferFuture.jl I get this error:

ERROR: CLError(code=-11, CL_BUILD_PROGRAM_FAILURE)

I'm not certain yet- but I think the kernel in rand.cl is incorrect or somehow the kernel source is being corrupted.

At least I've narrowed it down to the offending method call in rand.jl :

``` julia
p = cl.build!(p, options=string("-I", joinpath(dirname(Base.source_path()), "../", " -w")))
```
