显示缺少llvm-config配置，需要安装llvm。
由于系统不同，配置不同，编译方法不同，这个问题很少出现。不出现就不用管，出现的时候安装即可。
未安装gcc
Mac一般自带了gcc，不用自己安装，Linux系统一般需要手动安装，不过安装也很简单，一行命令即可
命令sudo yum install gcc
[centos@ip-172-37-13-154 ~]$ sudo yum install gcc

完毕！

未安装blibc-2.18
直接运行官方的release包，可能会报如下错误
./paramcache: /lib64/libc.so.6: version 'GLIBC_2.18' not found (required by ./paramcache)
[centos@ip-172-41-16-181 filecoin]$
出现这个错误就需要，安装glibc_2.18。
先下载glibc源码包
curl -O http://ftp.gnu.org/gnu/glibc/glibc-2.18.tar.gz，用tar解压，再进入解压后的文件夹，在其中新建一个名为build的文件夹，
tar zxf glibc-2.18.tar.gz
[centos@ip-173-21-19-221 ~]$ cd glibc-2.18/
[centos@ip-173-21-19-221 glibc-2.18]$ mkdir build
[centos@ip-173-21-19-221 glibc-2.18]$ cd build/
[centos@ip-173-21-19-221 build]$
进入build文件夹，依次执行命令
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make -j 8
sudo make install
这几步花费的时间会比较长，需要耐心等待。
