Linbox was updated from 1.1.6 to 1.1.7 before I became involved with
it. Judging by the changelog, though, the problem is that 1.1.6
failed to build due to requiring an old version of givaro and 1.1.7
fixed the build problem: I became involved when the same problem
occurred; givaro was updated, and then linbox 1.1.7 failed to build.
I contacted upstream about the problem, and they suggested moving to
linbox 1.2.1, which did solve it. The move to linbox 1.2.2 was
coordinated with another new release of givaro.
In short, moving backwards in linbox versions will require also moving
backwards in givaro versions.
Ok. 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/713663b790...

repoquery --whatrequires foobar
Or, to find the total set of affected packages:
repoquery --whatrequires --recursive foobar
The repoquery command is provided by the yum-utils package.
Thanks!

Hmmm, that puts us in a difficult position. Fedora is all about being
on the cutting edge, so moving backwards in versions is ... painful.
What might be reasonable is to make new packages, linbox11 and
givaro32, containing linbox 1.1.6 and givaro 3.2.15, respectively, for
the use of sage. That way we can keep the newer versions around for
anybody who might be using them, but still support sage. What do you
think?
givaro should be ok, but by contacting upstream we hopefully should
have all components working together. I just reported in sagemath trac:
