The package containing / using an older libtool is indeed probably the 
problem, using autoreconf and libtoolize --force, is not the solution I 
would advice though, esp. when the package is using older stuff as then 
this often will fail. In my experience the autoxxx stuff is best "left 
alone" (see the recent breaking of packages with the new intltool for 
packages which re autoconf-ed, but did not re-auto inittioolized for 
example).

The better way to fix this is to add the following two lines to your 
specfile after %configure:
sed -i 's|^hardcode_libdir_flag_spec=.*|hardcode_libdir_flag_spec=""|g' 
libtool
sed -i 's|^runpath_var=LD_RUN_PATH|runpath_var=DIE_RPATH_DIE|g' libtool
