George Hartzell 4d72e0fb9d Make the cpanm version a variant ... Rather than hard-coding the verison of `cpanm` that's [optionally] installed into the core, make it a variant with a default value of '1.7042'. Also discovered that `prefix + 'bin'` is the same as `prefix.bin`, so embetter that bit of code.		2016-08-02 11:16:46 -04:00
