error "Missing parentheses in call to 'print'" with python3.11.2 on OSX

[dsisson]

I get the following traceback message when trying to run a module that imports castro:

tests/examples/test_website.py:4: in
from castro import Castro
E File "/Users/derek/dev/v3/lib/python3.11/site-packages/castro/init.py", line 110
E print "Running ffmpeg: encoding and creating keyframes"
E ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
E SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

I see 4 print statements missing the parens. I'm running python 3.11.2 on OSX 12.6.3.
