need xlisp help

[Kenton Lee]

I'm sorry if this is the wrong group for this.  I'm not going to
post it to net.sources.

I collected the latest bunch of xlisp files from net.sources and am
having trouble making it on System V.  The files all compile OK,
but when I get to the link, it can't find a routine called "index".
Does anyone know what this is or where I can get it.  Thanks much.
