it means exactly what it says.  what's interesting is _why_ it can't
find it.

it's probably an indexing problem.  if your old systems were that old,
they likely didn't use an index; modern systems use variants of ls-R
files as a sort of simple-minded database of the files available.
modern systems _don't_ therefore look up files in directories.

tell us what systems you're talking about --- the answer is different
for different systems.

if it's tetex-based, you may get some help from

page isn't deemed quite "ready" yet)
