ii libc6 2.3.6-0ubuntu20 GNU C Library: Shared libraries and Timezone data

in ubuntu libc is in the following pachages:
libc6
libc6-dev
libc6-i686
witch when i uninstall it removes also the package ubuntu-minimal


so is it there a solution ?

I cant uninstall my system!!!! i mean it!
with
php < /dev/null
i get no errors
my PHP is versioned 5.1.2

i have apache
Server version: Apache/2.0.55
Server built: May 29 2006 01:52:53
installed
after installation of ISPconfig..... my server on the address
https://________:81/
can not go from main ISPConfig page (index.php) to login.php (wants me to download a file named login.php ) - witch is empty!


Also i noticed that At the end of a NOT FOUND web page
I GET THESE:

Apache/2.0.55 (Ubuntu) mod_auth_kerb/5.0-rc6 DAV/2 SVN/1.3.1 mod_fastcgi/2.4.2 mod_jk/1.2.14 mod_ldap_userdir/1.1.8 mod_mono/1.1.10 mod_python/3.1.4 Python/2.4.3 proxy_html/2.4 mod_ruby/1.2.5 Ruby/1.8.4(2005-12-24) mod_ssl/2.0.55 OpenSSL/0.9.8a

SOULDN'T there be a mod_php (parammeter) ?
i know that ISPConfig makes it not default to apache.
so i guess the error is from ISPConfig , right ?
