package_data question

[Miki]

Hello All,

I'm trying to add package_data from outside the package directory.
The current project looks like:
.
|-- __init__.py
|-- a
|   `-- src
|       `-- py
|           `-- __init__.py
|-- b
|   `-- src
|       `-- py
|           `-- __init__.py
|-- c
|   `-- src
|       `-- py
|           `-- __init__.py
|-- dlls
|   `-- c.dll
`-- setup.py

I'd like to get c.dll inside the p.c directory, so I wrotefrom
setuptools import setup
setup(
   name='p',
   package_dir={
       'p' : '.',
       'p.a' : 'a/src/py',
       'p.b' : 'b/src/py',
       'p.c' : 'c/src/py',
    },
    packages=['p', 'p.a', 'p.b', 'p.c'],
    include_package_data=True,
    package_data = {
        'p.c' : [ 'dlls/c.dll' ]
    }
)

However c.dll is not copied.
build/lib.linux-x86_64-2.6
`-- p
    |-- __init__.py
    |-- a
    |   `-- __init__.py
    |-- b
    |   `-- __init__.py
    `-- c
        `-- __init__.py


Any idea how to fix this?
(Changing the directory structure is not possible - not my project).

Thanks,
