向大家求教： 我在执行 rvm pkg install readline 时，出现了如下提示

Extracting readline-6.2.tar.gz to /home/fengfans/.rvm/src Applying patch '/home/fengfans/.rvm/patches/readline-6.2/patch-shobj-conf.diff'... Prepare readline in /home/fengfans/.rvm/src/readline-6.2. Error running 'autoreconf -is --force', please read /home/fengfans/.rvm/log/readline/autoreconf.log Configuring readline in /home/fengfans/.rvm/src/readline-6.2. Compiling readline in /home/fengfans/.rvm/src/readline-6.2. Installing readline to /home/fengfans/.rvm/usr

我查看了 autoreconf.log 日志，

请问是什么原因，如何解决。
