[tex-live] texconfig behaviour (repost with subject line) (Modified

[Ury Passy]

Dear Mr Gerben Wierda
I need your help!
For years I was using the software Textures by Blue Sky. However, with 
the introduction of Mac OSX I switched to TeXShop. I downloaded your 
i-Installer but I do not know which package is required for the Latex 
to recognize epsfig.
I wrote the following:
\documentclass[11pt,emtex]{article}
\usepackage{epsfig}
\usepackage{changebar}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{latexsym}
But I got:
!LaTex Error: Unknown graphics extension: .eps
l.393 \epsfig{file=5_points.eps,scale=0.5}
?
Could you help me please?
Thanks
