I believe that Camm Maguire, the Debian maintainer of the atlas2
packages, tweaked the makefile for atlas to produce shared libraries.

The atlas developers don't like shared libraries because position
independent code takes a performance hit.  Their objective is to get
the absolute best performance so they only produce static libraries.

You may want to get the sources for the Debian atlas packages and look
at what Camm does in the makefile.  I am Cc:'ing Camm on this reply in
case he wants to add anything.
