What you want is:

lm := LayoutMorph newColumn.
lm separation: 10.
b1 := LabelMorph new contents: 'short'; color: Color white.
b1 layoutSpec offAxisEdgeWeight: 0.
lm addMorph: b1.
b2 := LabelMorph new contents: 'very long'; color: Color white.
b2 layoutSpec offAxisEdgeWeight: 0.
lm addMorph: b2.
lm openInWorld.

The off-axis wheight is a property of the submorph layoutSpec. Not of 
the outer LayoutMorph. See `LayoutMorph example2`.

BTW, play with, read the code, hack the code around. Do this with all 
the LayoutMorph class side examples. They are there to help you.

Cheers,
