Pier on Visualworks

I am excited about trying Pier, but I have a bit of an investment in code I have written in Visualworks 7.6 versus Squeak. I tried loading the Pier bundle from the Cincom public repository, but got lots of errors. I found that if I pre-loaded Magritte, things went a little better, but I am still getting errors. Is the Visualworks version of Pier a dead end? Am I missing some dependencies? Should I use an older version of Visualworks? Should I just port my code over to Squeak? If the Pier bundle on the Cincom public repository is good, then let me know and I'll post my specific errors to try to work through it. Thank-you.
