ports 安裝 tripwire 不行 - BBS

煩請各位指教 , 這是哪方面的問題

OS type : 4.11-release
安裝方式 : ports
version : tripwire 2.3.1.2
在安裝之前有用cvsup更新ports tree , 也有用portupgrade
error message如下:

Checking for programs specified in install configuration file....

/usr/sbin/sendmail exists. Continuing installation.

/usr/bin/vi exists. Continuing installation.
