Hi Monks, Inside this makefile, I have a variable 
asdf = aaa bbbb c

or 

asdf = ddddd ee asdfg

[download]
I want to use a single perl command to generate 
bbbb_aaa_c

or 

asdfa_ddddd_ee

[download]
where this output is based on the length of the longest element to the shortest (if equal then, alphabet order). How to do this?
