grdvector -I is misbehaving
|Target version:||Candidate for next bugfix release|
The -I option used to have no checking and could crash for incorrect arguments, but the check we added fails when trying to determine if the desired vector interval is a multiple of the grid interval.

Actually, there was one more bug. For geographic grids using the new geovector, the directions obtained from dx, dy were not converted to azimuths first. Also, -T is not valid with geographic data (no checking and giving a warning). In r12490; not sure what that does to your macports build update.
