  I think this is the major showstopper for now.

  Jerry, do you think it is reasonably to downngrade and use
linbox 1.1.6? Patching should be possible, but not much
trivial, quick guess would be to use mpz interfaces for the
apparently now deprecated or available elsewhere or other
interfaces, integer matrix operations.

  Sorry for more fedora newbie questions, but how do I query
what requires a package? E.g. in Mandriva I can use

urpmq --whatrequires foobar

asking it to know what, if anything requires linbox.

  sage 5.0 will also use linbox 1.1.6 from what I understand, or at
least should be what is used in alpha builds.

Thanks,
Paulo
