Um. I did. I wrote one. I said so.
Now, are we talking about the same thing?
I used the example of the DRVConfig/PostgreSQL, Oracle and MySQL
code to create a libPvPsqlS.so which included the
ODBCINSTGetProperties function. I added it as the Setup DLL
using ODBCConfig. I proved it worked by using ODBCConfig to
configure a Pervasive setting.

What? am I misreading the code?
In odbcinst/SQLConfigDataSource.c it seems quite clear to me that
it looks for the Setup DLL, looks for the ConfigDSN function in
the Setup DLL (not the driver DLL) and calls that. So I added a
ConfigDSN to my setup dll and I see that it does indeed get
called. That's when I started getting confused.
I grepped for ConfigDSN and saw references in the MySQL and
PostgreSQL code, e.g in Drivers/MySQL/setup.c. Now I presume I
can't build that yet since I don't have the Qt libraries, but I
presume that is the source code of the driver library, which is
NOT where SQLConfigDataSource looks.
That.. is why I am confused.
I'm looking for an explanation rather than spending hours trying
to set up the build. I know, I'm lazy.
