I believe shipping a mapping file with Galaxy (& galaxy-lib) is a good
way to go - there is an existing github issue on this:

https://github.com/galaxyproject/galaxy/issues/1927

Hopefully this could be made generic enough to be useful with other
resolvers such as environment modules and future resolvers such as
Debian packages.
