[PROJ] test failure with 6.2.1

[Greg Troxel]

I ve been paged out from proj (for non-geo reasons :-( ) and am trying
to catch up.  I saw the RC notice, so my first step was to update
pkgsrc-wip from 6.0.0 to 6.2.1, before trying the RC.  It builds fine,
and tests go ok until:

which seems non-trivial.  I would have thought this was in Canada, but
it seems like just north of Bozeman, Montana.

Are tests of 6.2.1 expected to pass?  With the following grids, or
something else?


This is with the following grids included:
                proj-datumgrid-1.8${EXTRACT_SUFX} \
                proj-datumgrid-europe-1.4${EXTRACT_SUFX} \
                proj-datumgrid-north-america-1.2${EXTRACT_SUFX} \
                proj-datumgrid-oceania-1.0${EXTRACT_SUFX} \
                proj-datumgrid-world-1.0${EXTRACT_SUFX}
