Problem to upgrade from OCSng 2.1.2 to OCSng 2.2

HI,

My current configuration : Debian 6 with OCSng 2.1.2.

I tried to upgrade today but it did not work : I have got this message :

Where is Apache Include configuration directory [/etc/apache2//etc/apache2/conf.d/] ?
*** ERROR: /etc/apache2//etc/apache2/conf.d/ is not a directory !
*** ERROR: /etc/apache2//etc/apache2/conf.d/ is not writable !

I do not understand the rights on these directories did not change and are :

drwxr-xr-x  2 root root  conf.d

drwxr-xr-x  8 root root apache2

Where is the problem or the mistake ?

This is the first time I have a problem with a OCSng upgrade !

Thanks in advance !
