在升级到gcc4.9.1时 make check出现的错误

make[1]: Entering directory /home/he/gccbuild'
make[2]: Entering directory/home/he/gccbuild/fixincludes'
autogen -T ../../gcc-4.9.1/fixincludes/check.tpl ../../gcc-4.9.1/fixincludes/inclhack.def
/bin/bash: autogen: command not found
make[2]: *** [check] Error 127
make[2]: Leaving directory /home/he/gccbuild/fixincludes'
make[1]: *** [check-fixincludes] Error 2
make[1]: Leaving directory/home/he/gccbuild'
make: *** [do-check] Error 2

autogen没有安装

装一下就好了
