Could you attach your config.log as well? Your main.log says:

:info:configure checking for sbrk... yes

and:

:info:configure checking that sbrk is (now) non-random... cannot trap sbrk

On my Intel Mac, it says:

:info:configure checking for sbrk... yes
:info:configure emulating sbrk for mac

The code in ​configure.in disables the use of sbrk on Intel macOS. The version of gcl we have in MacPorts predates the existence of Apple Silicon Macs. Maybe the use of sbrk should be disabled on Apple Silicon Macs too.

I did not see any changes to this in configure.in in the latest version of the software but I will still try updating the port to the latest version.

Hi Ryan, config is now attached. Let me know if you would like anything else. Regards

Ok thanks. I was just curious whether sbrk existed at all on Apple Silicon Macs. I noticed that on my Intel Mac the log said sbrk was deprecated, and we've seen some other long-deprecated things finally removed on Apple Silicon. But that doesn't appear to be the case here. Rather, the test is just failing because it is trying to use sbrk without including the header where it's declared:

Replying to ryandesign:

I will still try updating the port to the latest version.

I'm not able to build 2.6.13 or 2.6.14 at all and filed this bug report about it: ​https://savannah.gnu.org/bugs/index.php?63844
