在github上下载的google protobuf 2.5.0分支编译问题
由于没有configure文件，需要使用autogen生成，autogen依赖gtest所以
wget https://codeload.github.com/google/protobuf/zip/v2.5.0
mv v2.5.0 protobuf_2.5.0.zip
unzip protobuf_2.5.0.zip
cd protobuf-2.5.0
修改autogen.sh，
##注释curl http://googletest.googlecode.com/files/gtest-1.5.0.tar.bz2 | tar jx
##改为：
wget https://codeload.github.com/google/googletest/zip/release-1.5.0
unzip release-1.5.0
mv googletest-release-1.5.0 gtest
./autogen.sh
./configure
make
