Whoa!  By all means use sudo as a user-specific way of permitting
superuser execution of some programs.  But NEVER grab a program of
this type off the net as a binary and simply run it, particularly
if it's granting root access such as this one is.  You don't know
what's in a binary, or who might have deposited it on the web site
(including those who break into web sites and deposit "interesting"
binaries for the unsuspecting to download).  Get the source code,
see what's in it, and then compile that for your system so that
you know what you're dealing with and be assured that it's compiled
for the specifics of your system...particularly when such programs
get near the kernel.  Think security, as well as function.
