Sure.  You can build the py36 ports you want in addition to the regular 
py27 ones.  Just add the port name(s) to your build list appended with 
'@py36'.  It's generally safe to have both python27 and python36 
packages of the same module installed simultaneously -- just remember to 
use 'python3' on the command line or in shebangs.
