I did try removing the system libdvdnav just to be sure that they are
not being linked into by mistake, but it does not seem to make any
difference. When looking what linker does, it includes 
-L../libmythdvdnav and -lmythdvdnav-0.22 and in
../libmythdvdnav/libmythdvdnav-0.22.a at least there is this string
present:

root at mythtv:~/mythtv/mythtv/libs/libmythdvdnav# strings
libmythdvdnav-0.22.a |grep dvdnav_get_serial_string
dvdnav_get_serial_string
dvdnav_get_serial_string

One would think that linker would find the function from the
libmythdvdnav-0.22 but no.. Strange.
