这是因为gpg key是Fedora 16版本的，降级回13的话需要用到13的key，上网搜索了下找到了之后放到/etc/pki/rpm-gpg/覆盖RPM-GPG-KEY-fedora-i386之后再重新运行上面的命令即可(记得备份原文件，降级完成后要把文件还原的，要不然系统升级会有问题)。
最后为了防止系统每次自动把make更新回3.82，我们在/etc/yum.conf里再添加一行来过滤掉make的自动升级
exclude=make
3. 缺失的系统工具
我的fedora16安装的时候选择的是software development的配置安装的，编译的时候出错需要安装的工具包括
sudo yum install gperf
4. 编译过程中的错误
a) perl错误
Can't locate Switch.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at external/webkit/Source/WebCore/make-hash-tools.pl line 23.

这个错误是由于fedora16中新的perl版本将switch的module拿掉了，需要修改webkit的源码来编译通过:进入external/webkit的目录，打下面的patch

b) mutable错误
