GDAL crazy directory stuff

I have a file created by NSIDC with GDAL that can be read by GMT using 

	grdinfo foo.bin=gd

in some directories but not others. This is also the case with cmds like grdreformat.  :-(

Below for example I copy the file from the directory where things run, to another directory, and even run "diff" and verify they are identical, but GMT fails.

After wasting about a day on this, it seems like it must be the case that there is some strange permission issue for the GDAL extensions (or something).

Anybody ever seen this feature?
