[gdal-dev] ESRI's Mercator_Auxiliary_Sphere projection

My application uses the GDAL & OGR libraries to load maps containing projection
metadata. As part of testing, I tried to load a GeoTIFF image exported from ESRI's
ArcMap 10.0 using the default coordinate system, the resulting OGRSpatialReference
does not validate successfully. Is there a way to get this to work?
Here is the output from gdalsrsinfo for such a dataset:
> ERROR 6: No translation for Mercator_Auxiliary_Sphere to PROJ.4 format is known.
> Validate Fails - contains non-standard PROJECTION values
> PROJ.4 : ''
> OGC WKT :
It is quite possible that my application is not finding the appropriate
data files, but I didn't want to spend too much time investigating if this
projection is not yet supported. I did notice that the defect described at
http://trac.osgeo.org/gdal/ticket/3962 has not been resolved, and then there's
the absence of an AUTHORITY clause in the WKT, so I'm thinking maybe this isn't
