Huh.  I was basing this on having used the 'port select' stuff for gcc & 
python, looks like perl isn't using this feature.

$ port select --summary
Name       Selected  Options
====       ========  =======
cython     none      cython27 none
gcc        none      mp-gcc6 mp-gcc7 none
llvm       none      mp-llvm-4.0 none
nosetests  none      nosetests27 none
python     python27  python26-apple python27 python27-apple python36 
python2    none      python26-apple python27 python27-apple none
python3    python36  python36 none

$ port installed | grep perl5
   mosh @1.3.2_0+perl5_24 (active)
   perl5 @5.24.2_0+perl5_24 (active)
   perl5.20 @5.20.3_2 (active)
   perl5.24 @5.24.2_0 (active)

It looks like getting this to work with perl is more complicated and is 
still an open issue:
