could you confirm that xine-lib-1_rc5 works ?
xine-lib-1_rc5 also failed to compile on PPC (same problem) xine-lib-1_rc4_rc1 DOES compile on PPC
Adding -U__ALTIVEC__ to the CFLAGS forces the preprocessor to choose the correct code to compile. The other part is for the altivec-enabled gcc-2 IIRC.
Fix is in the CVS and will show up on the mirrors in a few hours. -U__ALTIVEC__ is always added to CFLAGS. If USE="altivec" is set, --enable-altivec is given to configure. If USE="-altivec" is set, --disable-altivec is given to configure (and disables the use of altivec).
