Short version: Please download build test *and install* DBI 1.613_71, then download build and test any compiled drivers you use to check they work with DBI 1.613_71.
Let us know about any failures *and* successes. Also grep the source code of the driver to see if it defines PERL_POLUTE. If it does, let us know. Long version: Perl 5.13.3+ removes support for PERL_POLUTE. PERL_POLUTE enables use of old-style variables names, without the PL_ prefix (e.g. sv_undef instead of PL_sv_undef). The DBI has, for many years, enabled PERL_POLUTE mode in DBIXS.h, so it's likely that compiled drivers are use some old-style variables names. These drivers won't work with Perl 5.13.3+. To aid testing for this, the DBI 1.613_71 doesn't enabled PERL_POLUTE mode. So please test compiled drivers against DBI 1.613_71. Thanks! Tim.
