`setup.py` should never attempt to import packages that are not yet installed, including packages from the source it is distributing. In this case, importing `get_version()` from `geraldo.version` was causing `reportlab` to be imported by side-effect (via `geraldo.__init__` which imports `geraldo.graphics`, besides other modules). However there is no guarantee that `reportlab` is already installed when `setup.py` is run, as it is the job of `setup.py` to specify `reportlab` as a dependency.
