>Description:
I was trying to reinstall Apache with db4 support when I found it impossible. 
Last lines was:
____
config.status: include/ap_config_auto.h is unchanged
config.status: executing default commands
sed: 1: "s,%%FTPUSERS%%,$FreeBSD ...": bad flag in substitute command: 'v'
*** Error code 1

Stop in /usr/ports/www/apache22.
*** Error code 1

Stop in /usr/ports/www/apache22.
____

I googled it and found that there are some users with the same problem, but no solution. (http://www.google.com/search?hl=en&q=+bad+flag+in+substitute+command%3A+%27v%27 first five links). What's more interesting - they have different versions of apache (20 or 22) and doing things like updating ports, cleaning configurations and other things like this does not help.
Then I found this "solution": http://forums.freebsd.org/showthread.php?t=3081 , moved my /etc/ftpusers to /etc/ftpusers.old and apache installs perfectly.

Unfortunately, I don't have skills or ecpierience to find what is broken in script that is executing sed command (don't even know which script could that be) but there is definitely a bug which shows itself in some strange occasions. 


>How-To-Repeat:
unknown
>Fix:
remove the /etc/ftpusers file from its location
