This could be valid bug, but then it depends on how NodeJS module installs are suppose to happen. If we are to package NodeJS modules that normally get installed with `npm` for use by all programs, then these should be installed in a search location. On the other hand, if you are only suppose to install globally system binaries, then those probably should not be accessible to all NodeJS programs. We can do a number of things here. But looking at Debian, their npm installs things in /usr/local prefix, not /usr. Perhaps changing `npm install -g` to install things under /usr/local and keep search path /usr/lib{,64}/node_modules for system installed modules would be a compromise here?
