compile problem in Documentation directory on Debian

[Reinhold Kainhofer]

For some time, I always get compile errors in the Documentation directory. 
This only happens on Debian machines (one with sid, the other with edgy), but 
not on a Kubuntu machine. Does anyone know the reason for this problem:

make[1]: Entering directory `/home/reinhold/temp/lilypond/Documentation'
make PACKAGE=LILYPOND package=lilypond -C user all &&  make PACKAGE=LILYPOND 
package=lilypond -C bibliography all &&  make PACKAGE=LILYPOND
