nonpareil @0.79: SyntaxError: multiple exception types must be parenthesized

[ryandesign (Ryan Carsten Schmidt)]

After updating scons to version 4.3.0 using python310, nonpareil fails to build:

scons: Reading SConscript files ...
  File "/opt/local/var/macports/build/.../nonpareil/work/nonpareil-0.79/SConstruct", line 123
    except OSError, (errnum, strerror):
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: multiple exception types must be parenthesized

I'm not familiar with python and don't know how to "parenthesize" this to make it work again.

This isn't actually multiple exception types that just need to be enclosed in parens, it's (old) python 2 syntax for getting at the contents of the exception object. See ​https://peps.python.org/pep-3110/
