Since I've been told before that sarcasm is unbecoming (though damn
funny), I'll explain a bit further.

Running ./configure and make as root can open your system to potential
threats if you're not careful. While somewhat unlikely, there may be a
root kit in the code, which building as root triggers. The bigger
threat comes from errors in the Makefile, or the code itself, such
that an errant cleanup script during the build process does an rm -rf
/* instead of an rm -rf $buildroot/* or some other similar flawed

Building as a normal user may also clue you in to other flaws in the
code, such as an inability to function for users other than root,
linking to a directory where it doesn't need access, etc.
