Gary,

I'm afraid I never looked into the original problem because your reference
to the files in question ("tiff files from the mapserver tutorial") was too
inconvenient to follow up on.  Can you provide a more direct reference to them?
What does gdalinfo report for one of the problem files?

The message means that the code used to translate WKT coordinate system
descriptions into PROJ.4 coordinate system descriptions does not know how
to do it for the provided coordinate system.  This might be for a reason
as simple as the coordinate system string being empty (unavailable).

Best regards,
