 Oh no! I discovered, after answering your second question, that pylint was
 not in my path (although I thought it was), and I realized how to fix the
 problem. Thanks for the help, and please close this ticket. I'll explain
 more below for anyone else who encounters this issue.

 1. Output of {{{port contents py27-pylint | grep pylint-2.7}}}:
 {{{
 /opt/local/bin/epylint-2.7
 /opt/local/bin/pylint-2.7
 }}}

 2. Output of {{{os.environ['PATH']}}} run in a console within Spyder:
 {{{
 '/usr/bin:/bin:/usr/sbin:/sbin'
 }}}

 The principal cause of my problem was that I was not starting Spyder from
 the command line. Instead, I had made the following AppleScript
 application (with the official Spyder icon) to start Spyder from the Mac
 GUI (Finder, Launchpad, Spotlight, etc.):
 {{{
 try
   do shell script "/opt/local/bin/spyder > /dev/null 2>&1 &"
 end try
 }}}

 What I just learned (and I did not know before) is that since I was not
 starting Spyder from the bash command line, the environment variables
 specified in my ~/.bash_profile were not being passed to Spyder. The
 solution was to emend the AppleScript application to "export PATH":
 {{{
 try
   do shell script "export PATH=/opt/local/bin:/opt/local/sbin:$PATH ;
 /opt/local/bin/spyder > /dev/null 2>&1 &"
 end try
 }}}
