>Description:
If Apache HTTPD 2.4 (www/apache24) is installed, attempts to build the www/mod_mono port will fail.  First, USE_APACHE is set to "22", not "22+", so the port infrastructure automatically sets BROKEN if APACHE_VERSION equals 24.  Second, if USE_APACHE is overridden by setting it to "22+" or "24", the build fails with the following errors:

mod_mono.c: In function 'apache_get_userid':
mod_mono.c:389: error: 'unixd_config' undeclared (first use in this function)
mod_mono.c:389: error: (Each undeclared identifier is reported only once
mod_mono.c:389: error: for each function it appears in.)

mod_mono.c:854: error: 'conn_rec' has no member named 'remote_addr'
mod_mono.c: In function 'send_initial_data':
mod_mono.c:1981: error: 'conn_rec' has no member named 'remote_ip'
mod_mono.c:2029: error: 'conn_rec' has no member named 'remote_ip'

I assume that this is due to mod_mono using deprecated parts of Apache's API.
