---------------------------+--------------------------------
 I use pygments through the MacPorts installation py-pygments package and
 after updating from 2.0.2 to 2.1 yesterday (a process that went off
 without a hitch) have run into an error. When I invoke `pygmentize -V` at
 the command-line I get the following:
 {{{
 Traceback (most recent call last):
   File "/opt/local/bin/pygmentize", line 5, in <module>
     from pkg_resources import load_entry_point

     raise DistributionNotFound(req, requirers)
 pkg_resources.DistributionNotFound: The 'Pygments==2.0.2' distribution was
 not found and is required by the application
 }}}

 That last line tells me `pygmentize` is looking for the wrong version. If
 I revert the py27-pygments (which py-pygments depends on) package to
 2.0.2_0 then the error goes away, but of course that's because I'm using
 the old version (I do not need to revert the py-pygments package).

 Using terminal for further investigation I did/got the following:
 {{{
 cd /
 sudo find . -name "pygmentize" -print -xdev
 ./opt/local/bin/pygmentize
 ./opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pygmentize
 ./usr/local/bin/pygmentize
 }}}

 Invoking each of these commands specifically, the first one fails with the
 above error while the other two work fine. Using `which` I find that the
 first and third are in PATH with the first (the one which fails) being
 first.  Further testing also shows that the third is a symlink to the
 second, but the first is a normal file.

 As a final check I do/get the following:
 {{{
 sudo find . -name "pygments" -print -xdev -type d
 ./Applications/calibre.app/Contents/Resources/Python/site-
 packages/pygments
 ./opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/pygments
 }}}

 The first pygments site-package is safely tucked away inside an
 application bundle, so it's shouldn't be causing the problems. The second
 is the MacPorts installed one.  Looking inside it, I can clearly see that
 the version is 2.1 after the update.

 My conclusion from all this is that `/opt/local/bin/pygmentize` was not
 updated properly when py-pygments (and py27-pygments) was updated from
 2.0.2 to 2.1.  What's my best course of action for fixing this problem?
