I see a couple things. First, you are missing a ":" after
"<IDL_DEFAULT>", but that shouldn't affect finding routines in $my_path/idl.
Check out the help for PATH_CACHE. IDL builds a cache of the .pro files
in the directories in the !path. If you slip a new file in later, you
have to manually compile it with something like:
IDL> .compile my_path/idl/my_routine
or rebuild the cache with:
IDL> path_cache, /rebuild
I usually just restart IDL.
