Avahi compilation help needed

[Sagara Wijetunga]

Dear FreeBSD community

I'm trying to compile Avahi-0.6.25 (http://avahi.org/) on FreeBSD 7.2 
(i386) [in fact, on Tomahawk Desktop]. It develops compilation errors. 
Is it possible someone to help us by compile Avahi and identify the 
compilations issues and propose relevant fixes. We use "./configure, 
gmake, gmake install" method. For an example, first compilation issue 
faced was <netinet6/in6.h> does not get included because 
-D_XOPEN_SOURCE=500 in the configure script.

We use D-Bus and Qt4 but do not use Mono. It may be doesn't matter to 
build on Qt3. Please help us to get Avahi compile cleanly. We can 
install and see whether it works or not.

Many thanks in advance.

Kind regards
Sagara
