Nope, you didn't read it right.

It will never work:
1) Your file needs to end in .env.
2) graceful does not restart the root process and the environment is kept in 
the root httpd process, thus you need to restart apache.

% alias aprestart
aprestart='sudo /usr/local/etc/rc.d/apache22 restart'

% cat /usr/local/etc/apache22/envvars.d/path.env
#!/bin/sh
export PATH=/sbin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin

% aprestart
