NS installation problem

[jlai@liman.RUTGERS.EDU (Jie Lai)]

Dear Sir,

When I install otcl (Version 0.96, September 95), I do "./configure" ok. But 
when I run "make", I got following error msgs:


big{jlai}80:make

Could someone tell me what's the problem and how to fix it? Your help 
is greatly appreciated.

Thanks.
