Lets take this in parts.
1. The guys at Rails seems to have switched to sqlite as the default
for the development environment. I don't know in detail why they did
that but for a limited situation where the application is being
reloaded every time, the inefficiencies of sqlite are outweighed by
other factors. Probably the simplicity of not managing a server
while doing "just" development has something to do with that.
2. I have BOTH sqlite and MySQL on my laptop.
When it came to install the Typo-5.1.2 gem the installer insisted
on compiling new(er) versions of BOTH the MySQL and the sqlite
At Dreamhost, which I still can't get the upgrade working and have
continued to report the problems here and identified them as being on
Dreamhost rather than the 'virgin' install on my laptop, I have
always run Typo with MySQL.

It is also perfect in the 'single user' development context as well,
which is, no doubt, why the Rails people recommend it as such.
But, as I said, trying to install Typo-5.1.2 on my laptop, which already
had the Ruby MySQL driver installed and a number of RoR applications
running using MySQL, most notably Radiant and the "What's next".
As far as Typo on Dreamhost goes, sqlite is NOT, repeat NOT, repeat NOT
being used. But when I took a dump of that database and tried
Typo-5.1.2 against it on my laptop, the gem still insisted on compiling
a new(er) version of the interface.
So the point I am making is not about the strengths or weaknesses of
sqlite vs MySQL; it is that I had functional versions of Ruby interfaces
for both and operating RoR applications using both, yet the gem install
of Typo-5.1.2 insisted on "upgrading" both sqlite and mysql drivers.
I've asked and I'm still asking: what is the deficiency in the old
drivers than necessitated this upgrade or is it just an artefact of the
way the gem was packed on that particular development machine?

Back when the RoR guys had MySQL a their default I used that.
As I said, the problem when I did the virgin install on my laptop was
that the instructions on the Wiki said to install the gem first. This
was before I had run "typo install ..." to create the
"config/database.yml". It was the install of the gem that raised the
dependency and required new versions of the MySQL and SQlite rivers to
be compiled. This has nothing whatsoever to do with any choice of
database I might or might not later make for the application. It holds
true even if then decide not to use Typo and leave the gem undisturbed.

Perhaps that slit should be there anyway ...

I've known how to play with UNIX for over 30 years and played with more
versions than are currently available.
I believe in diversity and only ran Wordpress since Dreamhost offered it
as a one-click install when I needed to get something up fast. When it
came to the Typo4.0.3 version I took great care and crafted and
customized and had a good time. I like Rials and I prefer Ruby and don't
think PHP is really OO. My mention of wordpress was as a comparison of
the ease of upgrade, not a comment on function or preference.

I tried upgrading the 4.0.3 installation using the instruction on the
Wiki and met with the problems I've documented in this thread. You'll
note it began with that and that's why I used the subject like "Problems
with upgrade" rather than with install.
I tried doing a virgin install following the instructions on the Wiki
and met the problems I've documented. The Typo documentation does say
in the README "Typo supports MySQL, PostgreSQL, and SQLite" but when I
describe the problems I have had with both MySQL and with SQLite I get
met with sarcasm and derision. I dread trying PostgreSQL.
