>Description:
	Building devel/p5-Term-ReadKey fails with
	Cannot find blib even in <WRKSRC>/../../../../..
>How-To-Repeat:
	cd devel/p5-Term-ReadKey && make build
>Fix:
	FreeBSD Ports report this to be a MAKE_JOBS issue
	(http://permalink.gmane.org/gmane.os.freebsd.devel.cvs.ports/306815) and
	add MAKE_JOBS_UNSAFE=yes (http://svnweb.freebsd.org/changeset/ports/354217).
	Adding MAKE_JOBS_SAFE=no to devel/p5-Term-ReadKey/Makefile seems to
	circumvent the problem.
