I see this as well on Monterey on x86_64 if I already have tk installed with the +x11 variant and I do not use trace mode. The solution would be to use trace mode:
sudo port -t install tk +quartz
I guess the problem is that -L flags are in the wrong order: -L/opt/local/lib precedes -L/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_x11_tk/tk/work/tk8.6.13/unix on the link line, thus -ltk8.6 refers to the existing installed copy of libtk8.6.dylib, not the one that was just built.
