You'd need to link to 64-bit libraries. If you can't find them, then please 
disable the the troublesome 32-bitlibraries. E.g.,

./configure --with-gif=no --with-xft=no CFLAGS="-m64 -g3"

should build without the abovementioned libraries.

That's "encouraging", in some sense. At least you can reproduce the bug.

This sounds promising. Can you use a debugger to find out what is going wrong 
inside rt_dldump?
