[Mono-list] Problem with mod_mono and Apache config file

[beniniva at csr.unibo.it]

Hi,
I try to configure Apache to load mod_mono module.
In the Apache config file I add the following line:

LoadModule mono_module modules/mod_mono.so

but when I type the command "httpd" to start Apache I got this error:

Syntax error on line 193 of /etc/httpd/conf/httpd.conf:
Cannot load /etc/httpd/modules/mod_mono.so into server:
/etc/httpd/modules/mod_mono.so: undefined symbol: ap_null_cleanup
[root at localhost ~]#

what I can do?

thank's

Valentina.
