You must use a version of MySQL at least as recent as Version 3.22.13

because that version fixes some portability problems under Unixware.

After this, you @strong{must} run 'make realclean' and then proceed with the

installation from the beginning.

If you want to use the Perl module on a system that doesn't support dynamic

linking (like SCO) you can generate a static version of Perl that includes

@code{DBI} and @code{DBD-mysql}.  The way this works is that you generate a

version of Perl with the @code{DBI} code linked in and install it on top of

your current Perl.  Then you use that to build a version of Perl that

additionally has the @code{DBD} code linked in, and install that.
