G'day kdgman,

Welcome to the monastery.

"I tried to install version 5.14.2 with perlbrew and it wouldn't work ..."

Take a look at the "App::perlbrew - Compiling Perl with thread support" thread. It covers 5.14.2 and was tested on Mac OS X.

[For future reference, posting things like "it wouldn't work" and not providing any details of what you did and the results you got, are not well received. See "How do I post a question effectively?".]
