julia Error loading custom modules

I am trying to load custom modules in julia, but I always get the following error: 

ERROR: foo not found
in require at loading.jl:47

where foo is a the following module:

module foo

bar() = "foo"
export bar

end

which is located at "/home/.../julia/modules/" and I also added:

push!(LOAD_PATH, "/home/.../julia/modules/")

to my ~/.juliarc.jl file. What am I missing? Btw, I also reinstalled julia v0.3.10, no effect.

One more thing, if I include the file, I can use the module:

> include("../modules/test.jl")
> using foo
> bar()
> "bar"

works. But it should not necessary, right?

naming the file as the module is a convention in Julia, especially when using using and import without including corresponding module definition file.

take a look at the definition of the function require which is implicitly called by using to load packages in the loading.jl below.

...
...
function find_in_path(name::AbstractString, wd = pwd())
    isabspath(name) && return name
    base = name
    if endswith(name,".jl")
        base = name[1:end-3]
    else
        name = string(base,".jl")
    end
...
...

if you run using foo, julia will look for foo.jl in the LOAD_PATH.
