我似乎无法在 rvm 下安装最新的 rubinius（rvm 似乎工作正常，其他 rubies 可以毫无问题地安装）。错误日志如下：
rbx-2.2.9 - #compiling - please wait

有谁知道这可能是什么？我错过了一些明显的东西吗？我试图运行的命令很简单：
rvm install rbx
由于它可能是相关的，因此前面还有一条额外的警告线：
No binary rubies available for: arch/libc-2.19/x86_64/rbx-2.2.9.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
这似乎只是说它是从源代码编译的（这不应该是问题）。系统是arch linux。
