If you are seeing the above error using cvs-head files, the problem 
identified has been resolved becuase there is no zlib-devel package 
installed.  To resolve this issue simply install zlib-devel and 
re-compile and all willbe good.  Thanks to Jer Jer on #asterisk for the 
assistance.

This issue only comes into play when you do a minimal install following 
the documentation on wiki.
