Eu estava tentando construir o eglibc-2.19, que baixei por meio de
apt-get source libc6
Eu segui as instruções INSTALL, mas recebi este erro quando ocorreu o nptl,

Eu também tentei em outro 14.04 LTS meu, também tenho o mesmo erro.

Alguém poderia me dizer como posso resolver esse problema?
Obrigado antecipadamente.
