[Neuroimaging] Nipy: How can I install Nipy v0.4.0 on ubuntu with pip?

[Michael Notter]

Hallo everyone,

If I use the command `pip install nipy` to install nipy on my Ubuntu 14.04.3 system, it only installs version 0.3.0 and not the newest version 0.4.0. 

According http://nipy.org/nipy/users/installation.html, I should use `sudo apt-get install python-nipy` to install nipy. But this would lead to the download of 40 new packages and a disk space increase of 706 MB. This seems a bit extreme, as I already have the dependencies Numpy, Scipy, Sympy, Nibabel and Matplotlib.

The new packages are the following:
  dvipng
  fonts-cabin
  fonts-comfortaa
  fonts-freefont-otf
  fonts-gfs-artemisia
  fonts-gfs-complutum
  fonts-gfs-didot
  fonts-gfs-neohellenic
  fonts-gfs-olga
  fonts-gfs-solomos
  fonts-inconsolata
  fonts-junicode
  fonts-lato
  fonts-linuxlibertine
  fonts-lobster
  fonts-lobstertwo
  fonts-oflb-asana-math
  fonts-sil-gentium
  fonts-sil-gentium-basic
  fonts-stix
  libwxbase2.8-0
  libwxgtk-media2.8-0
  libwxgtk2.8-0
  mayavi2
  python-apptools
  python-envisage
  python-nipy
  python-nipy-lib
  python-pyface
  python-sympy
  python-traits
  python-traitsui
  python-vtk
  python-wxgtk2.8
  python-wxversion
  tcl-vtk
  texlive-fonts-extra
  texlive-fonts-extra-doc
  ttf-adf-accanthis
  ttf-adf-gillius

This list might be so long, because I'm using anaconda, instead of enthought for my python distribution.

Is there a reason why I can't install the newest version of nipy with pip on Ubuntu?

Best,
Michael
PS:
 I just saw that the installation via github and the command `python 
setup.py install` works (with allot of "package missing" messages), but only if I first remove any older nipy 
version from my python/site-packages directory.
