Comment (by snhirsch):

 I was able to build Poco from the upstream sources, but when I went to
 build against it I ran into another problem.  It was corrected with the
 attached patch from their issues tracker.  I did notice compiler warnings
 referencing OSAtomicIncrement32 in the build log.

 Would definitely be neater overall if the ports package worked.  Let me
 know if there's anything else I can do to help?
