I suspect this is a libtool (http://www.gnu.org/software/libtool/ 
libtool.html) issue.  In your sources, you have version 1.5.22 which  
dates from 2005 (before the release of Intel Macs).  There has been a  
lot of work done on libtool since then to handle multiple archs.

If I were you, I would first try the 1.5.23b development version.  If  
that does not work for you, try the libtool list.
