[galaxy-dev] upgrading cufflinks version to 2.0.2

Hello, I am trying to upgrade cufflinks version from 1.3.0 to 2.0.2. I changed the directory in the PATH to version 2.0.2 but when I run cuffdiff on the galaxy it still uses the version 1.3.0. Do I need to change the code of the wrapper? Another question is how to I enable both version of cufflinks to appear and run on the galaxy? Thanks, Karen
