This is why a verified backup is mandatory. :-)

Manually messing with the source is not a good idea, especially
when you want to improve system security.

The easiest way to do this is to actually re-install the whole OS
(and then the applications you need). Doing this via source is
possible, but often more complicated than it needs to be. You
will have to manually download the source distributions, as FreeBSD
4 and 6 still use CVS for source checkout (which isn't supported
anymore and therefore won't work). Installing the currently required
tool for source checkout, which is SVN, isn't really possible because
FreeBSD 4 and 6 are lacking the ports toolchain which is required,
and binary packages probably won't exist for that old version (in
the archive I mentioned in a previous message).

No, you install the OS in the "normal" (binary) manner. To install
from source, you need a system that's able to process the sources,
which in your case would mean you'd first have to get the sources
of 5.0, compile and install, upgrade to lastest 5.x version, compile
and install, get sources of 6.0, compile and install, upgrade sources
to 6.2, compile and install - which is much more work than actually
using the precompiled 6.2 installation image and install "from scratch",
and after that, restore configuration and user data from backup.

As I said, it's possible, but much more work that it needs to be.
There's nothing wrong with installing "from scratch". From the
installation media, you can also install precompiled packages of
software you need. And everything else can be installed from the
ftp-archive location with $PACKAGESITE set for pkg_add.
Is there any reason for you not to install a _current_ FreeBSD
version, such as FreeBSD 10.2 for PPC? It will be much easier
for you to get the additional software you need: You can install
it binarily (via "pkg add") or from source with the ports collection
(which now has totally different "inner workings"). And you're
using an OS that is supported.
Happy FreeBSD user since 4.0
