The same happens when trying to use gcc11.

16. S. I have found the following and will try that: ​https://github.com/MoarVM/MoarVM/issues/1149

Replying to evanmiller:

I have fixed it:

36-73% port -v installed moarvm
The following ports are currently installed:
  MoarVM @2022.02_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-22T08:10:05+0800'

The following changes are needed for ppc. Add this to portfile:

PortGroup legacysupport 1.0
legacysupport.newest_darwin_requires_legacy 10

if {${os.platform} eq "darwin" && ${os.arch} eq "powerpc"} {
    configure.args-append --no-mimalloc
}

And add this patch:

+++ Configure.pl	2022-03-21 18:14:42.000000000 +0800

 # Probe the compiler.

The first addresses a lack of strnlen, arc4random_buf and mimalloc, the latter fixes configure failure.

And now I have nqp and rakudo built:

36-73% port -v installed rakudo
The following ports are currently installed:
  rakudo @2022.02_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-22T09:02:19+0800'

  nqp @2022.02_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-22T08:43:03+0800'

Very cool! I will propose the legacysupport stuff first since that affects Intel. Then I'll try your changes on PPC.

Did it work for you on PPC without a patch to configure?

A configure patch is needed for PPC. It is also needed for 10.7/10.8:

​https://build.macports.org/builders/ports-10.8_x86_64-builder/builds/83899

I'll see if I can put together a PR this morning.

Yes, it fails on Leopard otherwise:
