OK, I think the most *likely* answer is that the gpd file
is "corrupted" in the sense that it is missing (or maybe
has too many) ^M line control characters. The mapx
program has been known to choke under these conditions
and issue exactly this kind of "unknown projection" error.
This kind of corruption can be caused by improper settings
when doing an ftp of the file from one machine to another,
or by e-mailing the file, etc.

The easiest way to see these "problem" line endings
is to open the file in an emacs editor. Perhaps it is
best to download a "valid" gpd file from the NSIDC web
page and see what the endings are suppose to look like,
then make sure the endings of your gpd file match.

Let me know.

Cheers,

David
