asterisk users - Oct 2008 - 'Asterisk is not thread safe' message

I recently built Asterisk from scratch on Ubuntu (Ubuntu  
4.2.3-2ubuntu7). Everything seemed to build ok, but when I start
Asterisk, I get the message:

     Warning! Asterisk is not thread safe.

Is this anything to be concerned about? How can I make it go away? Is  
there an alternative threading library I can link against?

Thanks!

Joe

It's a very serious error, in that Asterisk detected that your mutexes are
not recursive.  They need to be recursive-enabled, or locking will simply not
work correctly.
