rkhunter errors

[Paul Cartwright <ale@pcartwright.com>]

I just got this error message back from my rkhunter cron job:
Warning: Application 'exim', version '4.69', is out of date, and possibly a 
security risk.
Warning: Application 'gpg', version '1.4.9', is out of date, and possibly a 
security risk.
Warning: Application 'named', version '9.5.1', is out of date, and possibly a 
security risk.
Warning: Application 'openssl', version '0.9.8g', is out of date, and possibly 
a security risk.
Warning: Application 'php', version '5.2.9', is out of date, and possibly a 
security risk.
Warning: Application 'sshd', version '5.1p1', is out of date, and possibly a 
security risk.


yet, exim is not installed, and ssh is:
ii  ssh                                                     1:5.1p1-5                           
secure shell client and server (metapackage)

which seems to me to be the latest package available to me in Lenny..
this is a brand new error message, never seen it before.
