Hello,  
I need Mmap in order to run the NIfTI package and when I run Pkg.test(“Mmap”), I get the following error message:

```julia
julia> Pkg.test("Mmap")
INFO: Testing Mmap
ERROR: LoadError: LoadError: UndefVarError: @unix not defined

I want to get around that by making some change by hand to Mmap.jl, does anyone know how I could do this?

Thanks,  
Philip

The path is there in the error - make the change to that file, then just add and commit it to the repo.

Edit: you probably want to make a new branch first, otherwise things might get hairy if you try to switch back.
