vim syntax suddenly stopped

[Prashant Kumar <prashkr@cse.iitk.ac.in>]

Hi all
All of sudden vim shows no syntax coloring :set syntax on is of no help.
Though ls --color is working fine. I recently upgraded ncurses could
that be the problem??

Any suggestion will be highly appreciated especialy from someone
who faced similar problem before
or Do I have to set some environment variable ?? i use testing
version of vim and debian both
TIA
