APM: Perl Online Survey software?

[David Bluestein II]

Anyone familiar with any online survey software written in Perl (or any 
other OS language)? I'm looking for something that will have:

  - ability to upload a client list and e-mail merge invitations to the 
people taking the survey (and later reminders e-mail to incompletes)
  - support for survey branching, skip questions, required questions, 
etc.
  - export data natively to SPSS
  - summarize data online to avoid separate data analysis

OR can be modified to do so fairly easily.

Thanks-

David
