You *really* don't want to do this!  The libltdl.so.1 in /usr/lib is
most likely the *32* bit library.  The libraries in /usr/lib64 are the
64 bit libraries.  It is important to understand that the '64 bit' ix86
processors (eg AMD64, IS64), also run in 32-bit mode.  BUT a given
process is either in 32 or 64 bit mode.  You can switch modes within a
given process and thus you cannot link a 64-bit program with 32-bit
libraries.  You are probably missing the 64-bit version of libltdl.so OR
somehow the install of libltdl placed the 64 bit library in with the
32-bit libraries.
