freebsd stable - Mar 2013 - lang/ruby19: ruby-1.9.3.392,1 is vulnerable: ** [check-vulnerable] Error code 1

I try to compile port lang/ruby19 and I always get on a FreeBSD
9.1-STABLE box the following error message, which is obviously triggered
by some port auditing - but I do not find the "knob" to switch it off.

Can someone give a hint, please?

Regards,

Oliver

I guess you sent it to -stable by mistake-- the knob you need is
DISABLE_VULNERABILITIES=yes.

I'm sure I don't need to lecture you on "Be careful with this"
