I haven't worked with this projection but I suspect you may have your
parameters set incorrectly.
> params=[6371200.0, 6371200.0,60.0000, -80.0000,0.0,0.0]
The first two values are the semi-major and semi-minor axis of your
"ellipse" are the same.

You may want to use the WGS84 parameters
> params=[6378137.0, 6356752.3, .....
Or which ever datum you selected when you set the projection directly
in ENVI.
