gobject-introspection-0.10.6_0 fails to build. At the point where errors appear in the log (attached), the output is:

:info:build OSError: [Errno 13] Permission denied: '/Users/wes/.cache/g-ir-scanner/06e881d3462dd6af89e7002a4fe05682b10d8021'

The console output is:

The actual relevant error in the log seems to be:

:info:build OSError: [Errno 13] Permission denied: '/Users/wes/.cache/g-ir-scanner/06e881d3462dd6af89e7002a4fe05682b10d8021'

So this is probably a consequence of the new privilege-dropping code in MacPorts 2.0.
