做CLFS第10章，编译sed出错，为什么我老是出错？

root:/sources/sed-4.1.5# CC="gcc ${BUILD64}" ./configure --prefix=/usr \

See `config.log' for more details.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by sed configure 4.1.5, which was
generated by GNU Autoconf 2.59. Invocation command line was

 $ ./configure --prefix=/usr --bindir=/bin --enable-html
