The vestigial "pythonw" symlink synonyms for "python" have been removed 
upstream in python3.4.  It looks like "port select" needs to be changed 
to accommodate that.

You should also be careful about setting "python" to a Python 3 variant.  
That's not recommended as many Python packages still assume that 
"python" refers to a Python 2 variant.  "port select" should provide a 
"python3" name as well and, ideally, for future compatibility, a 
"python2" one as well so that someday "python" can mean "python3", all 
as recommended in Python PEP 394.
