I'm stuck here!

I went through the Pine Makefile coz I recollect it giving me a warning 
about Pine not recommended by the FreeBSD Security Officer. And I also 
went through the Porter's Handbook (very briefly). From these two I learnt 
about the "pkg-install" file and so I tried putting in something there to 
popup as a warning after the first warning.

/usr/bin/dialog --msgbox "_WARNING!_ Turning the PASSFILE option on is 
very dangerous and should probably not be done, except on single user 
systems!" 7 70

But thing is -- how do I make this warning appear *only* if the PASSFILE 
option is chosen? From what I can see, the "WITH_PASSFILE" variable is not 
visible to the "pkg-install" file and so I can't use that to wrap the 
dialog around an if ... fi block. Any ideas?

Thanks,
