This is not a default install, as you are using the universal variant. Do you really need this ? If not try installing without it.

[FaradayLight (Faraday Light)]

Hi, It is my understanding that this is the default install on arm64 - the default was set to +universal in one of the recent updates to MacPorts.

[cjones051073 (Chris Jones)]

I am not aware of any changes to enable universal by default on arm, and I would be surprised if that change had been made. I also see no evidence to suggest this is the case in the recent builds on our arm buildbot

[FaradayLight (Faraday Light)]

At some point the option was activated in my variants.conf around the end of May and I know I did not add the setting.

[FaradayLight (Faraday Light)]

I will attempt the install without the +universal variant.

[FaradayLight (Faraday Light)]

OK, that installs the non-universal variant.

Looking at the output of the info I get the following:

Faraday, remove +universal from your variants.conf (and the reinstall all your ports, which will download buildbot versions). Then you will have no, or at least much less, trouble.

well I am not aware of anything in base that would have made this change for you ....

Hi, I can do that and would appreciate it if that prevented the difficulties I have encountered but why would it have been set in the first place? Before last weekend I did not know enough about MacPorts to find confirmation files so some component must have uncommented the setting in the conference file.

I can understand that, but nevertheless something applied the change.

[cjones051073 (Chris Jones)]

As far as I know, that change could only have been made by hand.... Nothing would have done it automatically.

Until last weekend I would not have know where to find that file and I only found out after reading-up on MacPorts because the problems I have been having.

[FaradayLight (Faraday Light)]

OK thanks for everyone's help - commenting-out the setting has addressed the problems I was having.

Great, glad we were able to help!
