When you have multiple versions of a port installed, which you do for libunwind-headers, you must specify which version you want to uninstall when you uninstall. You did this once for 3.5.0_3; do it again for each other version you have installed. Or just run:

sudo port -u upgrade libunwind-headers

to upgrade libunwind-headers to the latest version and uninstall all older ones.
