Try setting IDL_PATH to +/usr/local/idl/lib/local;+/usr/local/idl/lib.
(The "+" in front of the first one is in case it you add any subdirectories
to it.)
I do this on my IDL/Windows system (where the search order is controlled by a
PATH setting in IDL.INI) and IDL appears to construct a !PATH system variable
in which the local subdirectory occurs only once, at the start.
