[Mapserver-users] ogr broken perhaps? Problems with on-the-fly and other projections.

I have been trying to get a latlong shapefile produced by the usgs from
a UTM dataset (grs80 nad83 zone 18N) to display on a raster layer in NY
State Plane East (epsg:32115) projection , map base projection also set
to epsg:32115. My failures have led me to reproject my data manually
using gdalwarp and ogr2ogr. I have confirmed the projections by using
ogrinfo, gdalinfo and by actively plotting the results. The ogr utility
(manual and on-the-fly) puts all my latlong points at negative state
plane coordinates at a very reduced scale and far off "center" (by
several region diameters). I have tried working with the false eastings
and northings, but with no luck. Gdal seems to get this info (if it is
needed) from the headers; rasters seem to project both on the fly and
manually, though I have to assemble more files and templates to test this.
I have tried TRANSFORM=TRUE and =ON, no luck (which is it, by the way?
both appear on the doc sites and in postings) and evrything else I can
think of or have seen posted.
There is an old reference to version 3.3(something) being broken in this
regard.
Any insights?
