[mythtv] cannot find -ldvdnav

[Paul Webster]

I'm having a problem compiling the latest SVN of mythtv (8904)

libs/libmyth is complaining that it cannot find -ldvdnav

Prior to compiling myth, I downloaded and extracted libdvdnav-0.1.10,
./configure'd, make'd and make install'd successfully to --prefix=/usr

...
/bin/sh ../libtool --mode=install /bin/install -c  libdvdnav.la
/usr/lib/libdvdnav.la
/bin/install -c .libs/libdvdnav.4.0.0 /usr/lib/libdvdnav.4.0.0
(cd /usr/lib && rm -f libdvdnav.4 && ln -s libdvdnav.4.0.0 libdvdnav.4)
(cd /usr/lib && rm -f libdvdnav && ln -s libdvdnav.4.0.0 libdvdnav)
/bin/install -c .libs/libdvdnav.lai /usr/lib/libdvdnav.la
...

confirmed the existence of said files and the fact that /usr/lib is in
/etc/ld.so.conf
ran ldconfig again for good measure

Short of giving mythtv ./configure --disable-dvd, what else can I do?

Thanks
