setup calls install_data
On win32 setup.py calls install_data which copies the file into the egg - even though I have given the absolute path to sitepackages
C:\> python setup.py install
....
running install_data
creating build\bdist.win32\egg
copying TEST_FILE.TXT -> build\bdist.win32\egg\
....
On Linux the file is copied to the right path:
$ python setup.py install
.....
installing package data to build/bdist.linux-x86_64/egg
running install_data
copying TEST_FILE.TXT -> /mnt/data/home/stu/.virtualenvs/tmpv/lib/python2.7/site-packages
....
*something* is normalising my absolute path to site packages into just '' - it's possible to see by looking at self.data_files in the 'run' function in:
distutils/command/install_data.py
- on windows it the first part has been changed to '' unlike on linux where it's the absolute path I set... still not sure where it's happening though.
*This all took a while, as rebuilt VM and verified on 2.7.8 and 2.7.9..

linux it ends up inside the site packages as intended.
At a guess it seems like there might be a bug in the path handling on windows.
.. I wonder if it's something like this

which seems an easy way to get an off-by-one error in a path ?
