[Zope] pcgi on Solaris 2.6

Howdy - I'm trying to move a pcgi application from Linux to Solaris. The app works fine under pcgi on Linux, and also works fine using ZopeHTTPServer on either Linux or Solaris. However, when I try to start it under pcgi on Solaris, I get the following relevant bits from the html source: (102) failure during connect <!-- Interrupted system call pcgi-wrapper-version 2.0a5 --> Any ideas, everyone?
