missing dependency for port 'thefuck'

[psylum (Perry Rajnovic)]

fresh install of port thefuck @3.30_0, on macOS 10.15.8.

Added alias to tcsh, and tested with a known 'fix' it supplies.

Expected Output:

$ cat code                                                 
cat: code: Is a directory
$ fuck
ls code [enter/↑/↓/ctrl+c]
<contents of code directory>

Actual Output:

$ cat code                                                 
cat: code: Is a directory
$ fuck

ModuleNotFoundError: No module named 'six'

After manually installing py38-six, the application works as expected. I believe the port deps just need to include py{version}-six.

there's a chance that MacPorts is missing the six dependency as a downstream dependency of a direct one, but i'm not sure which it would be expecting to have it from. it's not in the original requirements.txt, but it shows up in most issue tickets as being installed (from thefuck), and the code itself explicitly imports the six package in many source files.
