- Multiple versions of libtiff installed in different directories - Multiple versions of spandsp installed in different directories - Asterisk was built against a spandsp installed in a directory that is not in the library search path, while another version of spandsp is in a directory that is in the library search path. so, at run time the wrong library is picked up. Many machines will happily build and install a library to /usr/local, and then successfully like applications against it, even though /usr/local is not in the library search path. Dumb, but true. The installation information page for spandsp, at http://www.soft-switch.org/installing-spandsp.html , warns about these issues.
