[Dbix-class] Use of uninitialized value $mysql_ver in numeric lt

[Dave Howorth]

I'm just trying to run an old program on a new machine and it is
throwing this error:

Use of uninitialized value $mysql_ver in numeric lt (<) at
/usr/local/share/perl5/DBIx/Class/Storage/DBI/mysql.pm line 117,
<$__ANONIO__> line 3.

I've found

https://rt.cpan.org/Public/Bug/Display.html?id=81979

but that says the bug was fixed over two years ago in 0.08204. I have

# cpanm DBIx::Class
DBIx::Class is up to date. (0.082820)

So I thought I'd ask here before I do a lot of investigation. Hopefully
somebody will have an idea of what is going on :)

Thanks, Dave
