It looks like it's doing a 'universal' build of 'glib2' for both 'arm64' and
'ppc-intel/x86_64' architectures, which you probably don't need.

My understanding is that MacPorts no longer builds 'universal' by default [1].
Is '+universal' defined in your '/opt/local/etc/macports/variants.conf'?

[1]: https://trac.macports.org/wiki/FAQ#universal

The 'main.log' referred in the error messages may have more information.

You could try cleaning the 'glib2' build and specifically disabling the
'universal' variant [2] while installing glib2.

[2]: https://guide.macports.org/#using.variants

    $ sudo port clean glib2
    $ sudo port install glib2 -universal

I'd concentrate on installing 'glib2' before continuing to install
'gnuradio'.
