Which version of ActivePerl?

[C.E. Morrison]

  I am testing GnuCash 2.3.14 on a Win 7 x64 system.  The ActivePerl 
website ( http://www.activestate.com/activeperl ) has three versions 
available and no explanation (I can find) of which version should be 
used.  For use with GnuCash 2.3.14, which is appropriate, Version 5.8, 
5.10 or 5.12?

Thanks
