Subversion 1.0.1 unusable

[Jean-Baptiste Quenot]

Hello,

Since upgrading subversion from 1.0 to 1.0.1, my repository is not
usable any more:

svn: Berkeley DB error while opening environment for filesystem /usr/local/var/svn/db:
Invalid argument

The port options are:

    'devel/subversion'  => 'WITH_MOD_DAV_SVN=YES',
    'www/apache2'       => 'WITH_LDAP=YES WITH_BERKELEYDB=db42',

Is it a problem with Berkeley DB being incompatible with my repository?
How to know with BDB version to use with repository?

In /usr/local/var/svn/format, there is a number 3, is it the BDB version
number?

Thanks for your help,
