The uhd port installs version 3.15.0.0. The uhd-devel port installs version 20220728-4.2.0.1-321295fb. Which port did you install? Check with port installed name:^uhd. It sounds like maybe you installed uhd-devel but wanted to install uhd. If so, you can fix it with:

sudo port -f uninstall uhd-devel
sudo port install uhd
