Is this in Windows or Linux?

You very likely don't have the libraries required to build, then.  But
it's curious that cairo should be the only one available, since normally
there is libart and gdkpixbuf, if Dia was compiled with support for
them.  I wasn't aware that the Cairo plugin was even able to do png yet.
Hans must have come further than I thought... Have you tried with -t
png-libart or -t pixbuf-png?
