Hello Jorge,

This is on a local install of Galaxy? The problem with the tool install sounds to be similar to the one you are having with trinity. The core issue could be that the binary has not been installed. But first, you set up the installation as a production server? And again, just to make sure, you are running the most current distribution?
Distribution news:
https://wiki.galaxyproject.org/DevNewsBriefs
Initial set up:
http:/getgalaxy.org
Then to set up as a "production server" (meaning, customize):
https://wiki.galaxyproject.org/Admin/Config/Performance/ProductionServer

Some tool wrappers come with the Galaxy distribution, others you obtain from the Tool Shed. Of these, some tools (including many from a Tool Shed repository) will manage the installation of dependencies like binaries, but others require that you download and install the underlying binary yourself (true for any in the distribution and some in the Tool Shed).
This is what the dependencies are and where to find them (when a tool is in the distribution, or was, check the Tool Shed repository if that is where the tool is sourced from):
https://wiki.galaxyproject.org/Admin/Tools/Tool%20Dependencies
And this is how to incorporate it into your instance:

How to install tools from the Tool Shed:
https://wiki.galaxyproject.org/Tool%20Shed#Installing.2C_maintaining_and_uninstalling_tool_shed_repositories_within_a_Galaxy_instance

This was a question that is a good fit for the galaxy-dev@bx.psu.edu mailing list as well, so if you need help with installation, please post a new question there. The more specific you are about what the problem is, the easier it is for others to offer help (where in the installation process you are having issues, etc.). Both velvet and trinity can be resource intensive, so if you have trouble with them on a local install (run, but not enough resource - compute or memory), then moving to a cloud may be a solution.

Hope this helps!
