局域网安装了个SVN在checkout的时候报错
SSL handshake failed: SSL error: Key usage violation in certificate has been detected.
解决方法（亲测）：
1.如果你没安装wget先安装wget.
yum install rpm-build wget
2.wget ftp://ftp.icm.edu.pl/vol/rzm2/linux-fedora-secondary/releases/15/Everything/source/SRPMS/neon-0.29.5-2.fc15.src.rpm
3.rpm -i neon-0.29.5-2.fc15.src.rpm
在执行这句的时候可能有警告，不要管。
4.cd /root/rpmbuild
5.vi SPECS/neon.spec
找到43行：'--with-ssl=gnutls部分，修改为：--with-ssl（也就是去掉=gnutls）。
6.yum install gcc make expat-devel gnutls-devel zlib-devel krb5-devel libproxy-devel pakchois-devel openssl-devel
7.如果没有rpmbuild安装一下
yum install rpm-build -y
8.cd /root/rpmbuild/SPECS
rpmbuild -ba neon.spec
9.cd /root/rpmbuild/RPMS/i386（根据系统架构可能会不同)/
10.rpm -Uvh neon-*
