Mediawiki install problem

[Tyrael]

Hi guys, sorry for troubling you, but I have a problem, and I hope you can help me out.
I downloaded the latest stable relase from the official website, upload it, then the install script die s without errors, like in this topic:
http://forums.x10hosting.com/showthread.php?t=25703&highlight=mediawiki
The mediawiki install documentation mention about giving write permission for the config directory, but when I try setting 775, or 777 I get Internal server error (500)
If you can help me, please do so, and sorry for my english.

=> here you can see the broken installer.

Edit:
I found the root of the problem.
The wikimedia isn't ready for suhosin, or the suhosin isn't working properly.
When the installer tried to call some function, which was present in the suhosin function blacklist, the the interpreter exited without proper error message.
I edited the installer, so the critical (eval, dl, unix_uname) calls makes a check for suhosin or safe mode, before execution, and so, I could install it.
Now i see a white screen on the default wikipage, I think I will figure it out tomorrow.
If somebody needs, I could share the edited config/index.php & includes/Setup.php files.

good night
(Btw. I like this hosting, just fix this suhosin behavior)

Edit:
Here we go: The posix_uname was used once again in the includes/GlobalFunctions.php, edited this file too, and the wiki is working.
I hope I helped somebody with this monologe.
