 Nope :)

 Look before that...

 From the Portfile:


 {{{
 openssh root# grep -nC5 __APPLE_API_STRICT_CONFORMANCE Portfile
 80-    # the order of arguments to strnvis and considers everyone else to
 be broken.
 81-    configure.cppflags-append -DBROKEN_STRNVIS=1
 82-
 83-    # Use Apple's sandboxing feature
 84-    configure.cppflags-append   -D__APPLE_SANDBOX_NAMED_EXTERNAL__ \
 85:                                -D__APPLE_API_STRICT_CONFORMANCE
 }}}

 If I remove that second -D, the build gets further but still ultimately
 dies:

 **There's no file or directory anywhere on 10.6 with 'xpc' in its name.

 I'm not much of a C coder or MacPorts wizard, but is it possible to just
 make all the changes since the 7.9p1_2 version of the port conditional
 on the OS version being 10.7 or greater? Because this stuff just isn't
 working on 10.6 and likely never will.
