Those are two separate approaches:

With a "virtualenv", there is usually no need to tweak "sys.path" --
you simply install everything your project needs into the "virtualenv".

"sys.path" tweaks are typically employed with a "central"
Python installation, to have it look at non-standard places for
module/packages under specific circumstances.

A "virtual environment" behaves like a typical Python installation
(it is just somewhat isolated). Thus, there is no problem
to install a package developped in a "virtual environment"
into any Python environment -- aport from potential name conflicts
(choose appropriate names to reduce this risk).
