在已有python的系统中通过源代码编译升级python，在make install 时 出现错误：
Makefile:1092: recipe for target 'libinstall' failed
make: *** [libinstall] Error 1
是因为系统已有lib目录，需要改名，再make install
例如：
./configure --prefix=/usr/
mv /usr/lib/python2.7 /usr/lib/python2.7.org
make install
或
./configure
mv /usr/local/lib/python2.7 /usr/local/lib/python2.7.org
make install
# ls -alt /usr/local/bin/python*
