I've no experience with GeoServer but this would be *extremely* weird that you
would need to create an image pyramid for ECW, because, due to its compression
algorithm, ECW has "natural" pyramid in it. Other formats might require pyramids
however for good performance.

I would have thought that grabbing latest gdal_retile.py should work, but I
haven't tested. What are precisely the new errors you get ?

But anyway, I'd recommand not using FWTools. It is no longer updated
(corresponds to a developement version before GDAL 1.6.0 release). Use OSGeo4W
or grab the builds you can find at http://www.gisinternals.com/sdk/ to use the
latest & greatest versions.
