Solaris 7, new patches and procmail

I run Solaris 7, sendmail and procmail v3.13.1 on a Ultra5 workstation.  
A couple of days ago Sun announced some patches for Solaris 7 which I
installed.  Since then procmail has quit working, no log entries, no
messages, nothing.

Anyone heard of this or got any ideas how I can start troubleshooting
this?  BTW, The patches can't be backed out AFAIK.

Let me know if you need any more information.

Best,
-Steve
