We use the EPSG database as provided, however you may wish to check with
your data provider to determine what axis order is expected.
This is the usual reason thing are off in the woods - and your ellipsoid
has North / East axis order :)
http://docs.geotools.org/latest/userguide/library/referencing/order.html
There is a MetaCRS mailing list for OSGeo which tries to ensure all our
software gets along at this level. You may wish to ask there for more
background on what each is doing, and what they should be doing instead :)
