Sorry for the delay. I've been tied up with progressing some work on plperl
http://www.mail-archive.com/[email protected]/msg140671.html
http://www.mail-archive.com/[email protected]/msg140769.html

I hope to get to this in the next few days.

The t/zv*_*.t tests are wrappers for the main tests. They're written by
Makefile.PL.

The t/zvg_* test look like:

    #!perl -w
    $ENV{DBI_AUTOPROXY} = 'dbi:Gofer:transport=null;policy=pedantic';
    require './t/01basics.t'; # or warn $!;

the t/zvg_* test look like:

    #!perl -w
    $ENV{DBI_PUREPERL} = 2;
    require './t/01basics.t'; # or warn $!;

and the zvxgp_* test look like:

    #!perl -w
    $ENV{DBI_PUREPERL} = 2; $ENV{DBI_AUTOPROXY} = 'dbi:Gofer:transport=null;policy=pedantic';
    require './t/01basics.t'; # or warn $!;

This approach (of running the entire test suite with a pure-perl DBI,
via gofer, and a pure-perl DBI via gofer) forces the DBI::PurePerl and
gofer code to keep in sync.

The zvg_ and zvxgp_ failures are pointing out that DBI::PurePerl needs
updating.
