I had some similar issues getting XVMC to work correctly at compile 
time. In the end I had to 'make distclean' followed by
'find / -iname 'libmyth*' -print' and then some selective deleting. Some 
of the libraries are in locations which may not get cleared out by make 
distclean - thus leaving old headers which can confuse the build 
process. YMMV, of course.
