There's confusion here: The problem here is not with MacPorts or Fink. I have neither of them on my system. Just MacOS, some developer packages from Mac's install DVD, X11User.pkg from this DVD, XQuartz and Wine compiled myself (+ SuspiciousPackage.pkg, admitedly). That's all it takes to run into trouble.
Then the issue is that these packages are installed in an appropriate location, one that is not searched when attempting to dynamically load them. This configuration error is not Wine's fault, and even if we worked around it other apps that attempted to load them dynamically would have the same problem.
Note that I never said it was the user's fault, but that it's a configuration error. In my opinion the proper place to fix this is in the library installation itself, or in the distribution of Wine. Mike Kronenberg's package does that--cheers, Mike--but it's too different from mainline to be considered stock Wine. A MacOS bundle that addressed this but was built with no patches at all to git Wine would be a lot closer to what I want. --Juan
