Lilypond CVS fails on compiling

[Jefferson dos Santos Felix]

I have tryed to compile lilypond from the CVS but there's the follow error:

rm -f ./out/break-substitution.dep; 
DEPENDENCIES_OUTPUT="./out/break-substitution.dep 
./out/break-substitution.o" g++ -c   -DHAVE_CONFIG_H  
-DSTRING_UTILS_INLINED -Iinclude -I./out -I../flower/include
