kdiskmark compiles, runs but can't get admin priviledges

Has anybody tried using benchmarks/kdiskmark? It builds and runs, but
fails with what appear to be permission errors when run as a regular 
user, reporting "Could not obtain administrator privileges."  

Run as root, it can't find the scratchfile .kdiskmark.tmp even
if I create it beforehand, saying file not found.

It isn't obvious why administrator permissions should be needed
and I can't find a man page. It's also not obvious how to look
for readme files when using poudriere. 

Thanks for reading, and any guidance!
