Hi

If you install two versions of a plugin with the same URI you can't
select which one you load. It will just trow you a error. (duplicate
plugin found).

You could install them in different path (just use the ones you mention
above) and then use the environment variable LV2_PATH to point to the
ones you'll try.

This variable will be used by most LV2 hosts (if not all) to scan for
plugins.
