Yes, specifically it seems to be returning '' instead of
'/usr/local/bin' which was to be prepended to '/rateup'

Smells like permissions, if root can, and mrtg:mrtg can't ..

Assuming FindBin::Bin and/or MRTG-lib::SL doesn't need to run as root
(?), maybe not all of /usr, /usr/local and /usr/local/bin are world
readable/executable (o+rx), or maybe rateup itself isn't executable by
mrtg:mrtg?
Just a hunch, cheers, Ian
