p5.16-json-any @1.220.0 configure failure

[pcfmac@…]

Running XCode Version 4.6 (4H90b) and MacPorts 2.1.2 on OSX 10.8.2 Build 12C60 (primex @ #macports) I am inexperienced with perl, but I took a go at trying to run 5.16 over 5.12. In the process of building a dependency, json-any, for net-twitter, I encountered this build error. As recommended by the problem hotlist I have tried building with apple-gcc-4.2 with no success.

--->  Computing dependencies for p5.16-json-any

Error: org.macports.configure for port p5.16-json-any returned: configure failure: command execution failed

Attached in the log with more detail. This is the part which looks of interest
