[Mono-list] I need help with mod_mono

[Gustavo]

Hello,

I have this trouble when I try to start apache with mod_mono:

# service httpd start
Starting httpd: Syntax error on line 213 of /etc/httpd/conf/httpd.conf:
Can't locate API module structure `mod_mono' in file 
/etc/httpd/modules/mod_mono.so: /usr/lib/libapr.so.0: undefined symbol: 
mod_mono

I use a red hat 9 and I have updated the last packages from red carpet.

Here are the lines added to the httpd.conf file:

LoadModule mod_mono modules/mod_mono.so
MonoUnixSocket /tmp/mod_mono_server
Alias /mono "/usr/share/doc/xsp/test"

xsp runs fine...
I have got no idea what is wrong, where can I start looking?

Thanks in advance,
Gustavo.
