Comment (by YesNo801):

 Hi,
 Both environments are installed, qt5 and qt6
 Now I uninstalled all the qt6 environment and relaunched the gqrx
 installation:

 $ sudo port install gqrx +experimental +iqba

 This time the installation worked, gqrx being built without problems.
 Any idea why it interfered with qt6 even though it only depends on qt5?
 Thank you.
