make all lilypond-2.18.2// help2man --no-discard-stderr' if option outputs to stderr

[lux-integ]

Greeings,

I am new to this list. .I am attempting to compile lilypond-2.18.2 on a 
computer with these:-
--cpu  -amd64 3 cores
--os - linux BLFS(pure 64bit) linux-3.10.37, gcc-4.8.1 guile-1.8.8, help2man, 
dblatex3.2,ghostscript-9.06 (and other reqs to compile  lilypond )

I ran configure successfully but  'make all'  ends like so:-
#'--------------
/home/linteg/lilypond-2.18.2/build/scripts/build/out/help2man out/lilypond > 
out/lilypond.1
help2man: can't get `--help' info from out/lilypond
Try `--no-discard-stderr' if option outputs to stderr
make[1]: *** [out/lilypond.1] Error 127
#-------------

I have'nt a clue what the above means nor how to fix it 
AND as far as I know I have help2man installed  ( I installed this when I 
compiled/installed grub ages ago)

Help/advice would be greately appreciated.

sincerely
LuxInteg
