New install of rt3 on Redhat AS4.5/64 fails

Tried installing on a new server I just built and after starting apache,
get the following:

Can’t call method “HasRight” on an undefined value at
/opt/rt3/bin/…/lib/RT/User_Overlay.pm line 1209

Have run “make dropdb” and “make initialize-database” and still get this
error…

Any ideas on what to look at?

Thanks
