Providing a mysql connector extension on Linux that works independently of system mysql library versions - a pipe dream ?

No, I'm not failing, but ignoring that on purpose. See:

This is was a stupid idea in the first place. It never has been distro
independent, just ignoring the whole purpose of distros at all. The only
way that it ever can work half-reliable is expecting that the user has
*their* prebuilt binaries, and bundle all the 3rdparty libraries with
the matching ABI.
Just look at their history, look at how ugly eg. Oracle RMBS is packaged,
they never really understood the whole concept of distros and opensource
I simply *refuse* to accept their stupidity as an valid technical argument,
because I want good software quality.

Just ignore the precompiled binaries and et the distros handle building

If you want a stable system, choose a proper distros and take what they
provide. Otherwise you find yourself faster and deeper in the package
maintainer role as you expect.
In case your distros doesnt keep up with upstream fast enough, just jump
into the package manager role explicitly and do it right, provide upgraded
packages for your distro, through the distros build/packaging machinery.

Well, as it always has been, for all thousands of thousands of packages.
Trying to take binary packages from distro to another always has been
a russian roulette, because there never was such thing like an stricly
defined ABI (including virtually all libraries that somebody might require).

The demand is always coming from scopes of specific distros. Feel free
to provide updated packages for these distros.

Yes, because the whole approach of trying to provide distro-independent
is simply doomed to fail, as soon as shared libraries that cannot
guarantee long-term ABI compatibility are involved.
You're fighting against windmills.

By "official version" you mean the precompiled binaries ?
Well, it just was a matter of luck that they worked.
Actually, when I last tried on my Gentoo systems, they did *not* work.
"Normal users", that want a system that "just works", should choose
a proper distro for that.
