Hello my dear friend:
I am a linux lover,i am installing mono.
I am a chinese.
I would lile make a friend with you.
please mail me as quickly as possible.
Thank you very much. 
I installed it following the next step:
http://www.apacheworld.org/modmono/INSTALL
a) Install Mono 0.23
Install the Mono rpms from 
http://www.go-mono.com/download.html
b) Install Apache
httpd-2.0.40-8.i386.rpm
httpd-devel-2.0.40-8.i386.rpm
c) Install mod_mono0.3.6
http://www.apacheworld.org/modmono/
download  Red Hat 8.0 rpm,
d) XSP web server (0.3)  
http://www.go-mono.com/download.html
e) Configure Apache
Edit the /etc/httpd/conf/httpd.conf file and add the following:
MonoApplication /mono /home/user/mono/install/xsp/server/test
mkdir /var/www/.wapi/
chown apache.apache /var/www/.wapi
chmod 700 /var/www/.wapi
f) Start apache 
As root, type:
/etc/init.d/httpd start
g) Browse the examples
http://127.0.0.1/mono/index.aspx

 Now i can look  around those examples,
h) Start my application
Edit the /etc/httpd/conf/httpd.conf file and modify the following:
MonoApplication /mono /home/user/mono/install/xsp/server/temp
