Actually, with my test setup, I can't even build lilypond, because metafont 
already fails with some long pathes:

I created the path "/data/lilypond/This-is-a-very-long-path-to-the-lilypond-
source-directory/And-it-contains-several-long-sub-directories/Which-should-
break-the-makefile/Because-the-call-to-lys-to-telys-will-be-longer-than-the-
allowed-130000-characters/" and symlinked my lilypond sourcedir there. Then I 
configured an out-of-source build in /data/lilypond/build1 and ran make. The 
binary built fine, but metapost fails with a memory corruption in glibc! In 
particular:


address@hidden:~/build1/mf/out$ mpost -progname=mpost -ini 
/data/lilypond/This-is-a-very-long-path-to-the-lilypond-source-directory/And-
it-contains-several-long-sub-directories/Which-should-break-the-
makefile/Because-the-call-to-lys-to-telys-will-be-longer-than-the-
allowed-130000-characters/lilypond/mf/mf2pt1.mp \\dump

This is MetaPost, version 1.208 (kpathsea version 5.0.0) (INIMP)

Any idea?
