This looks problematic to me. PHP is licensed under the "PHP license",
which according to http://en.wikipedia.org/wiki/PHP_License is
incompatible with the GPL (and therefore I assume with the AGPL,
which is the new license of BerkeleyDB).

Therefore, linking PHP with BerkeleyDB version 6 creates a PHP binary
that cannot legally be distributed.

If this analysis is correct, I'd suggest one of the following options:

 * Drop the support for BerkeleyDB support in PHP.

 * Add a berkeleydb5 package that packages the last known non-AGPL
   version of BerkeleyDB, and use that for PHP.

Considering how useful BerkeleyDB can be with PHP, I'm suggesting the
first option.

Best regards,

Thomas
