Yes, it is true. Only 32bit binaries are able to link against
mplayer32's 32bit libraries (/usr/lib32/libdha.so.1
and /usr/lib32/mplayer/vidix/*). You cannot mix up both, 32bit and
64bit code [1].

Ehm, actually no. mplayer is an exception because the configure
script tries to detect the best CFLAGS/optimization flags for your
system. Normally you have to set CFLAGS/CXXFLAGS yourself. I would
recommend you to place the following lines at the beginning of
your xine32's build() function:

	export PKG_CONFIG_PATH=/usr/lib32/pkgconfig 
	# we want a 32bit C-compiler, C++-compiler and assembler
	export CC="gcc -m32"
	export CXX="g++ -m32"
	export AS="as --32"
	# use standard i686 optimization
	export CFLAGS="-O2 -march=i686 -pipe"
	export CXXFLAGS="-O2 -march=i686 -pipe"

Furthermore you need to specify two configure options:

--libdir=/usr/lib32 ==> Do not install files in /usr/lib!
--x-libraries=/usr/X11R6/lib32 ==> X-libraries are in lib32 not lib64!

What do you mean? You definitely need x11-32.
