Would it be best to create a 'pylint' group and use port select? This would reflect the developer's viewpoint:
> I'm kind of reluctant to handle this in Spyder's code (of course, if it's the only way, we will take action anyway) because there is absolutely no reason for MacPorts to differentiate pylint scripts depending on Python minor version number: after all, this script is an executable that should behaves exactly the same way on any Python version.

So I looked in /opt/local/bin and found 'pylint-2.7' which is a symbolic link to '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pylint'. Spyder displays "Please install pylint" in the PyLint Panel, which I suspect is because it can't find pylint. How do you set your environment so that programs like Spyder find python binaries?

>> I did some digging in the spyder script that checks for the existence of pylint. It looks to me that spyder checks for the binary in the User's path. This will return false since a symbolic-link to pylint, named 'pylint-2.7' is installed in '/opt/local/bin'; pylint being installed into '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pylint'. As a test, I created another symbolic link 'pylint' that points to 'pylint-2.7' and as expected, was able to use the pylint widget in spyder. It seems to me, a better way to test for its existence would use PYTHONPATH.
> Great, so it's a bug in the py*-spyder port(s) for not looking for pylint by its correct MacPorts name. Please file a ticket.
