Thank you Matthias and others who have responded. Kindly see some
comments inline.

That is indeed true, but the feature/bugs delta between 5.12.2 and
5.10.1 (probably so, because haven't actually checked, so this could
only be a matter of perception) doesn't look as "crucial" as the delta
between R10 / R14B, or even R13A / R14B... which was the case for
RHEL5.5 (prior) and Ubuntu 9.10 (latter).

Of course, but that means I must have the build system setup. This is
not a big inconvenience, but would be so nice to have prebuilt
binaries. My target installation platform was "minimal" server install
in virtualized guests, with a target of keeping disk-space/RAM usage
to a minimum.

I could build on a different machine and then install on target
servers, but it would have been more-convenient if I could avoid the
build stage altogether... especially if figuring out the right build
environment (given the choices and issues with multiple GCC versions),
isn't something I wish to indulge in at the moment.

Thanks for pointing those out. Looks like I needed to look bit
further/deeper... especially for FreeBSD under "ports" and for
RHEL/CentOS in EPEL.
