  Ok, I am still figuring out my way with fedora, so, currently still
running Fedora16 plus all updates, but plan to switch to rawhide shortly.
For now I am ok with rebuilding some packages, like polybori, or
already running a newer pari.

  Me too also waiting, otherwise, will take me some time to actually
run sagemath in Fedora and debug it myself, as I believe if there
is something wrong with the patch, it was my misunderstanding
of things like arguments in format "A_nr, A_nc, B_nr, B_nc" renamed
to "m, n, k" as the constraint is number of rows of A must match
number of columns of B (for multiplication), or missed some place
where there could be a double dereference or double free as
linbox 1.1.6 did allocate a buffer for every matrix row and
linbox 1.2.2 allocates a single buffer.

  Ok. Once a newer pari is available I will update the lcalc package,
but it is just a matter of applying the pari patch. Could add a
build requires versioned, but not required as if applying the patch
it would not build with an older pari anyway.
