Which is possibly not a great idea... as you now know <g>.

Generally speaking, using virtualenv (no-site-packages) + pip (with a
requirement file you keep in your project) is a GoodPractice(tm) when
it comes to dependencies.

Daniel already provided the simplest solution for this problem. For
more involved changes and assuming you prefer not to mess with the
third part app's code, you can also monkeypatch the relevant functions
in your own app.

Depends on how much you need to modify the third part app. Forking the
app is sometimes the best solution, but it means you'll have a hard
time keeping in sync with the original code when bugfixes and new
features will be released. Monkeypatching doesn't totally solve this
problem but from experience it makes for easier updates.

My 2 cents...
