Comment:

 We see the same error on the 10.7 buildbot worker:
 https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/37525/steps
 /install-port/logs/stdio

 And with libusb-devel also:
 https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/37526/steps
 /install-port/logs/stdio

 So I guess it needs `configure.c_standard 2011`.
