-------------------------------+-------------------------------------------
 I am back to efforts to fix Pythons 3.x for Leopard as ppc+ppc64. I have
 built now `python38` and `python39` as `+universal`:

 {{{
   python38 @3.8.13_0+universal (active) requested_variants='+universal'
 platform='darwin 9' archs='ppc ppc64' date='2022-04-01T01:06:28+0800'
   python39 @3.9.12_0+universal (active) requested_variants='+universal'
 platform='darwin 9' archs='ppc ppc64' date='2022-04-01T00:21:32+0800'
 }}}

 However installing modules fail. As an example:

 {{{

 During handling of the above exception, another exception occurred:

 It is unclear why this happens. Any advice will be greatly appreciated.

 P. S. With `python27` universal is working with no issues:

 {{{
 svacchanda$ port -v installed py27-curl
 The following ports are currently installed:
   py27-curl @7.43.0.3_2+universal (active) requested_variants='+universal'
 platform='darwin 9' archs='ppc ppc64' date='2022-04-01T01:24:12+0800'
 }}}
