php5 with php4

I tried to install php5 with php4. I have php4 as module.
I tried to install php5 that:
# ./configure --with-curl --with-curl-dir=/usr/local/lib --with-gd --with-gd-dir=/usr/local/lib --with-gettext --with-jpeg-dir=/usr/local/lib --with-kerberos --with-mcrypt --with-mhash --with-mysql=/usr --with-pear --with-png-dir=/usr/local/lib --with-xml --with-zlib --with-zlib-dir=/usr/local/lib --with-zip --enable-bcmath --enable-calendar --enable-ftp --enable-magic-quotes --enable-sockets --enable-track-vars --enable-mbstring --enable-memory-limit --enable-fastcgi --enable-force-cgi-redirect --prefix=/usr/local/php5 --with-config-file-path=/usr/local/php5
# make
# make install
No errors, then i add this to httpd.conf
AddType application/x-httpd-php5 .php5
ScriptAlias /php/ "/usr/local/php5/bin/"
Action application/x-httpd-php5 "/php/php"
And when i upload .php5 file i getting Internal Server Error:
