总结一些FreeBSD安装Ports时会遇到的问题

1. make install之后，进入了config界面，但是里面有些package也许并不需要，并且可能造成安装失败。这个时候如果再make install却不会再进入config界面。解决办法：

make config install clean

2. 有时重新安装一个port，会提示类似

You may wish to ``make deinstall'' and install this port again by ``make reinstall'' to upgrade it properly.  If you really wish to overwrite the old port of ... without deleting it first, set the variable "FORCE_PKG_REGISTER"     in your environment or the "make install" command line.

这时可以make reinstall FORCE_PKG_REGISTER="yes"

3. 更新ports:

portsnap fetch extract update

4. 寻找一个port的位置

whereis py-django

..keep updating..
