[Modules] GnuTLS: Cannot create DBM Cache

[Antonio-Blasco Bonito]

I'm running apache 2.2.9 on Debian. I would like to have Name Based SSL
Virtual Machines so I installed libapache2-mod-gnutls 0.5.1
Then I created the folder:
drwxr-xr-x 2 www-data www-data 4096  7 ago
11:00 /var/cache/apache2/gnutls_cache/

Apache crashes as soon as started and syslog says:

[Thu Aug 07 11:21:49 2008] [error] (120002)APR does not understand this
error code: GnuTLS: Cannot create DBM Cache at
`/var/cache/apache2/gnutls_cache'
(120002)APR does not understand this error code: GnuTLS: Post Config for
GnuTLSCache Failed. Shutting Down.

Please help.
