编译glibc的时候错误,求助!!

emerge system的时候,到glibc的时个错误,提示如下:
call stack:
ebuild.sh,line 1557 : call dyn compile
ebuild.sh,line 966 : called src compile
glibc-2.4.ebuigure,line 1258 : called toolchain-glibc-src-compile
glibc-2.4.ebuigure,line 257 : called glibc-do-configure 'nptl'
!!!failed to configure glibc

编译Xorg时某一个文件也出现类似的错误,请各位高手帮一下忙,看如何解决:ask
