The perl test suite was added by Kai Kang as a custom solution "perl-tests" at the same time ptest was merged. (Bug #3296) Saul Wold asked Kai to update it to ptest and he agreed to do so Jan 16 but apparently has not had time to do it yet.
Fixed. http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=73b752897d8a4a9159d056d0c905e9076c30fcea
