Bug 177784

When trying to launch mongod using rc script located at /usr/local/etc/rc.d/mongod it fails and dumps backtrace 
to console. As might be seen in "mongo-start-sudo.txt".
MongoDB has stock configuration; no specific options in /etc/make.conf were point. Only WITHOUT_X11=Yes.

Fix: There is a some workaround. If mongod rc script starts under su - everythyng goes the right way. So

% sudo -s
% su -l
% /usr/local/etc/rc.d/mongod start

This will get us properly started mongod - "mongo-start-sudo-su.txt" and "sockstat.txt"
