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

Echoing what @ryandesign wrote: looks like uhd-devel was installed, not uhd. A minor tweak to his check ... try: port installed name:^uhd and active to get the currently active installed uhd port. I've actually tried this recently, and saw what you note, so I think @ryandesign is correct.

Hi Everyone. Thanks for the fast reply. Finally found the problem. seems like brew installed a version before.I havn't clean it all up.

Good catch! I was about to note that you have a non-MP UHD install somewhere, based on the [INFO] line -not- containing MacPorts. Closing this ticket.
