can't build pulseview (Slackware current)

Hi, I upgraded to Slackware current on 2021/01/01 and I can't build pulseview. I have built and installed all of its prerequisites that needed building. I did not rebuild qt5. I am using sbopkg and the latest version of Ponce's repository. I have included the last few lines of output from the build hoping this will help. Any help/suggestions is greatly appreciated. Thank you.
