safe_mode

hi,

today I tried to make pmwiki work on a host running php in safe_mode.

My problems:

* when I have pmwiki create wiki.d, it cannot subsequently write into it.
The message is:

Warning: file_exists() [function.file-exists]: SAFE MODE Restriction in
effect. The script whose uid is 660 is not allowed to access
/www/pmwiki-0.5.5/wiki.d owned by uid 30 in
/www/pmwiki-0.5.5/pmwiki.php on line 211

* when I create wiki.d manually, I have to chmod 777 to make it work. This
doesn't really seem safe to me.

* diff does not work.
