Massimiliano Culpo 8864d145e9 module files: system paths are excluded from path inspection (#5460) ... closes #5201 Currently, if a user sets an external package to have a prefix that is one of the system paths (like '/usr') the module files that are generated will prepend '/usr/bin' to 'PATH', etc. This is particularly nasty at the time when a module file is unloaded, and e.g. paths like '/usr/bin' will be discarded from PATH. This PR solves the issue skipping system paths when a prefix inspection is made to generate module files.		2017-09-25 09:47:50 -07:00
