"undefined reference" compile error in 2.11.60

[Kilian A. Foth]

Hello world,

I can't seem to get lilypond 2.11.60 compiled with GCC 4.0.2 on Linux 2.6.13.

The final linking step fails with 

  ./out/axis-group-interface.o: In function 
`Axis_group_interface::relative_pure_height(Grob*, int, int)':
  /home/foth/src/lilypond-2.11.60/lily/axis-group-interface.cc:182: undefined 
reference to `Align_interface::has_interface(Grob*)'
  ./out/beam-quanting.o: In function `Beam::quanting(scm_unused_struct*, 
scm_unused_struct*)':
  /home/foth/src/lilypond-2.11.60/lily/beam-quanting.cc:190: undefined 
reference to `Align_interface::has_interface(Grob*)'

and seven more undefined references to symbols in the Align_interface
class. Do these functions exist somewhere other than the many object
files in lily/out/, or is my C++ version subtly incompatible?
