The easiest way to add additional packages, is probably to download fenics-developer-tools, set up a custom profile and run fenics-install.sh
with this profile:
git clone https://bitbucket.org/fenics-project/fenics-developer-tools.git
cd fenics-developer-tools
editor install/profiles/fenics.Linux.yaml # add scipy
./install/fenics-install.sh install/profiles/fenics.Linux.yaml
Use fenics.Darwin.yaml
instead of fenics.Linux.yaml
if you are running OS X.
PS: I am currently writing some more detailed instructions about this, which will be added to the website soon.
