Thank you for the report. This is indeed a problem if you initially
build and install into a world-writeable directory
(e.g. /tmp/nmap-5.21/debian) and then copy the files elsewhere as part
of a distribution. This feature is meant to set the module path for
cases where people install Nmap in nondefault (but secure) locations,
such as their home directory. But it isn't a very important feature,
and we may be able to support that in other ways. So we have removed
the set_modules_path function and the call to it from
nmap/zenmap/setup.py in our source code repository. That change will
be in future Nmap releases, and here is the patch:
Modified: nmap/zenmap/setup.py
