CLISP 2.47/amd64 can't build "pari" module

Trying to compile with gcc 4.3.2 using this configuration:

./configure --prefix=/usr --libdir=/usr/lib64 --with-ffcall --with-dynamic-modules --with-module=wildcard --with-module=rawsock --with-module=bindings/glibc --with-module=clx/mit-clx --with-module=dbus --with-module=gdbm --with-module=gtk2 --with-module=pari --with-module=pcre --with-module=zlib --hyperspec=http://www.lispworks.com/reference/HyperSpec/ builddir
