Problem importing python file from current directory

I have tried the solution suggested on #48 , but it is not working. I am using Julia 0.6.2 on Windows with Python 2.7 and the program is

```
using PyCall
unshift!(PyVector(pyimport("sys")["path"]),"")
@pyimport Leitura_Sistema_REDS as ls
```

and I get the error message

```
ERROR: LoadError: PyError (ccall(@pysym(:PyImport_ImportModule), PyPtr, (Cstring,), name)

The Python package Leitura_Sistema_REDS could not be found by pyimport. Usually this means
that you did not install Leitura_Sistema_REDS in the Python version being used by PyCall.
