I was trying to install ggplot using pip install ggplot. As it turned out, I was missing many essential packages, like stated in  SciPy and blas and in SciPy with pip. After running 
sudo apt-get install build-essential gfortran libatlas-base-dev python-pip python-dev I didn't get these "Cannot build wheel" errors anymore, luckily.
Now as I am trying just pip install scipy (which I need apparently) it fetches the package informations and gets stuck at Running setup.py install for scipy ... /. I can't imagine it takes this long time to install a 12 MB package (I waited for 30 minutes). Pip won't list it, so it's not isntalled. Does it really take so long? Or do I have another problem here, now? What am I missing?
I am running python3.4 on Ubuntu 14.04.
EDIT:
When trying pip install ggplot it gets stuck at the setup.py install for scipy too...
EDIT2: It seems installing the package scipy for python3 did the trick. It is just completely unclear, why I need so many different packages from different sources to just get it to run. Anyhoo, scipy works and ggplot as well.
