FreeBSD 8.2安装Nginx1.0.1报错

使用ports安装的：cd  /usr/ports/www/nginx，然后make install clean
===>  Giving up on fetching files: nginx-1.0.1.tar.gz
Make sure the Makefile and distinfo file (/usr/ports/www/nginx/distinfo)
are up to date.  If you are absolutely sure you want to override this
check, type "make NO_CHECKSUM=yes [other args]".
*** Error code 1

Stop in /usr/ports/www/nginx.
*** Error code 1

我发现portsnap是从http://ftp.freebsd.org/pub/FreeBSD/ports/local-distfiles/osa/下载文件，但该目录下貌似只有nginx-1.0.0.tar.gz，根本没有nginx-1.0.1.tar.gz存在……
portsnap fetch extract update后应该都已经是最新的了……
