Actually, I have been carrying patches for newer givaro with linbox 1.1.6 and sagemath in Mandriva for quite some time. There is this request to update givaro http://trac.sagemath.org/sage_trac/ticket/9511 and it appears to have been updated, causing linbox to fail :-) http://trac.sagemath.org/sage_trac/ticket/12349 I just sent an email to linbox-devel asking for some help in integrating linbox 1.2.2 with sagemath 4.8 or newer, see http://groups.google.com/group/linbox-use/browse_thread/thread/713663b790d0dfe9 >> Sorry for more fedora newbie questions, but how do I query >> what requires a package?
