Well, GLIBC_PRIVATE is a private glibc interface intended for use by various parts of glibc itself, it can change (and does change from time to time) without providing backwards compatibility, any symbol in GLIBC_PRIVATE can disappear or change its semantics during glibc update. Consequently, packages are not allowed to have dependencies on GLIBC_PRIVATE. -- ldv
