Probles with procmail 3.12

I installed procmail 3.12 yesterday, and have a problem.  I am installing on 
Solaris 2.51. Now, executing:

/home/mcmaster/bin/mailstat -l /home/mcmaster/Mail/log

Yields:

  Total Average  Number Folder
  ----- -------  ------ ------
awk: syntax error near line 17
awk: illegal statement near line 17

Any idea what is wrong?
