Minimum required DBI version

[Kristis Makris]

Hello,

The Bugzilla installation section claims that DBI 1.38 is the minimum
required version to get Bugzilla working. 

http://www.bugzilla.org/docs/2.22/html/installation.html#install-perlmodules

We discovered that under Windows if one uses a DBI that is < 1.50 to
talk to Bugzilla 2.20 (previous releases work fine), and one happens to
fork multiple processes that use the DBI, the DBI exits unexpectedly. 

This is documented in:

http://bugzilla.mkgnu.net/show_bug.cgi?id=646
http://bugs.activestate.com/show_bug.cgi?id=45411

In any case, I wanted to give you a heads up. This might come up if one
builds additional tools in Windows that use Bugzilla. Perhaps the
minimum required DBI version should be 1.50, and not 1.38.
