cpanm --test-only fails on older versions

[pryrt]

When running tests at home, 5.30 worked (berrybrew/perls/system), but when I tried in any older version, it had problems with memory allocation for strings. I need to look into that more before a v0.007 release

And today, with start berrybrew use 5.xx.xx_x, all of 5.28, 5.24, 5.20, 5.12, and even 5.10 worked with cpanm --test-only. I don't know what the difference is... maybe it was the start, or maybe because I only set AUTOMATED_CI_TESTING on v510 (because I needed easy access to a 32bit). But http://metabase.cpantesters.org/tail/log.txt shows those correctly being submitted, so there will be some passing tests in the matrix tomorrow.
