nebmake.pl works only orthorhombic cell?

i am wondering if the standard nebscripts works only for orthorhombic supercell ( three supcell vector orthorhombic perpendicular to each other)?

I had a great experience using, for example, nebmake.pl to do calculations for orthorhombic supercell , eg

POSCAR:
xxx
1.00000000000000000
15.3612480163570009 0.0000000000000000 0.0000000000000000
0.0000000000000000 15.3612480163570009 0.0000000000000000
0.0000000000000000 0.0000000000000000 30.0000000000000000

but strange behaviors start to come up when I move to a rhombic unit cell ( |a|=|b|, a, b angle=60 degree, c perpendicular to ab plane)

If you have an example of the script failing, please let us know. It should work for non-orthogonal unit cells.
