	I agree. TH is resetting INC and the directories passed
	into test_harness() are lost after the first invocation.

	The simple test script below, when tested twice, fails on
	the second call. As you'll see, blib/lib is not in INC.

		 _____ t/foo.t
		/ #!/usr/bin/perl -w
		| use strict;
		| use Test::More qw(no_plan);
		| 
		| use_ok('Device::Profile::Document');
		| printf("INC:\t%s\n", join("\n\t", @INC));

	If you prepend the perl or (make test) command with
	(env PERL5LIB=blib/lib) the tests will work.
