Please tell that person that he is wrong :-)
There are multiple reasons:
* In general, in Python the try/except idiom is preferred over the
check-then-do idiom. See also
https://docs.python.org/2/glossary.html#term-eafp
* is_package_installed() is a hack: it is slow, it doesn't check for
versions (you cannot detect if somebody installed gambit-0.0.1 instead
of gambit-42.11) and it doesn't work with packages installed through
easy_install, pip or other means.
