It's a problem in the linking stage.

I've run into this before, and I don't know why it happens.  The order 
of the list of .a files seems to matter, so one .a file must come before 
another so that its functions may be used by that object file (or 
perhaps vice versa).  You can see I don't really understand the problem :-).
The workaround is generally to list these .a files twice.  This is 
already done for some .a files, but not all (this is done for civserver 
as well as civclient).
Try this patch.

Perhaps someone can find some documentation on this somewhere?  How is 
it supposed to be done?
