As long as the package you need doesn't include a C extension (which most don't) you can just ship it with your code (license permitting ofc.) - just add the path to the libary to sys.path. It's not a very clean solution but can be a real life saver when you have to work on "broken" systems.

Sorry, I wasn't clear. This is a system I log into every day, and I don't want to maintain my own install of Python and related packages on it. It's too much overhead. I'd rather just use the default Python, even though it's old.

For simple libs I just dump the py file/folder in the same folder as the script and import.
