You'll need to map your Trinity transcripts back to your reference genome using something like Blat or Lastz, convert the mapped transcripts to GTF format, and then run Cuffcompare.

You can run Lastz in Galaxy, but it's not clear to me how to convert Lastz's output to GTF format, especially the format required by Cuffcompare. You might try emailing the Cufflinks' authors directly or the Trinity mailing list for some ideas.
