I forgot to say that Galaxy installs those dependencies (tool_dependencies or conda) beside your host system.
That will not interfere with your host libraries, binaries ...

Hi Tony,

Yes, Galaxy will install a whole functional python version.
At runtime, Galaxy source some env.sh files according to the different requirements and the bunch of requirement dependencies.

Using the tool_dependencies, indeed, Galaxy sets almost a dedicated environment for the tools.

The purpose is the same with the new system Conda. But in this case, Conda can create environment natively

I hope I answered to your question.

I have galaxy server 15.10 running on Ubuntu 14.04, which has python 2.7.5.

I was in the process of adding matplotlib from the toolchest. It has a
dependency on package_python_2_7.

Before proceeding, I'd like to understand a bit how that works. Does that
install a whole new python, and how then does it get invoked?
