Settings like 'net-mgmt_flow-tools_UNSET= GCC' only apply to the options
defined by the port, and net-mgmt/flow-tools doesn't define a 'GCC' option.

Where the port Makefile says:

USE_GCC=any

it means the port will (in preference order)

   * use the version of gcc specified in DEFAULT_VERSIONS -- this
     defaults to gcc-4.9 at the moment

   * use an installed version of gcc from ports, where it checks each of
     the versions available from ports, preferring the oldest available
     one.

   * uses gcc from base

There is no longer any option to use DEFAULT_VERSIONS to specify the
base system gcc, since gcc is no longer in base for any supported version.

However, if you find that net-mgmt/flow-tools will compile and run
successfully with the system Clang, please submit a PR to have the
'USE_GCC' line deleted.

	Cheers,

	Matthew
