Well, you need xmlrpc to use the web interface and I think rtorrent is
going to complain abou their availability, because it is compiled with
xmlrpc support. . I have witten giTorrent (
http://code.google.com/p/gi-torrent/
) for hat purpose and xmlrpc needs to be compiled in to enable it. I
have a full package of XMLRPC 'advanced' that also includes the
development stuff. The reason for the 'advanced' version was that it
did not support the correct variable types in the other version and I
used w-torrent then that did not take to that nicely when the value
returned did not fit that variable type. So, I have a xmlrpc package
that contains both the libraries (all of them for the advanced
version), the tools and the header files. Dispose of the stuff you do
not need (probably just the libraries you have now in an updated
version).
