    Submitted By: Tushar Teredesai <tushar@linuxfromscratch.org>
Date: 2005-06-14
Initial Package Version: 1.2.2
Origin: Gentoo ebuild?
Upstream Status: Not submitted
Description:
 1. Build shared and static lib in one pass
 2. Always add -fPIC when building shared lib, don't expect the user to set it.

To build the shared and static library:
	./configure --prefix=<prefix> --shared &&
	make &&
	make install
Remove the --shared if you don't want the shared lib.
