Update from rc6 to svn

[aseques]

After a lot of "stracing" i finally managed to discover why I couldn't open the man login screen.
It's not the first time it happens to me after an upgrade. (Without entering to the control panel, I could not do the update of the database)
The variables were not replaced (at least using nightlyupdate), so I had a path in /etc/apache2/mods-enabled/fastcgi_ispcp.conf ponting to "/var/www/fcgi/master/php{PHP_VERSION}-fcgi-starter
In wich step should be the variable replacement done? I am copied the working the ispcp.conf from /etc/ispcp to the svn directory hoping it was enough ...
