master Fixing the issue where nginx is wrong

The installation file suggests that there will only be
one nginx, and that it will be installed at /usr/local/nginx.

trying to run a different executable, but I have resolved
them for brand-new installations.
master Fixed a compilation issue with onion
master This line NEVER worked.

I think this was causing all sorts of issues with
uwsgi (and any others relying on these settings).
