MacPorts_Framework @ 1.2.1_1 destroot failure on macOS Mojave 10.14

[ylluminarious (George Plymale II)]

I attempted to install Pallet on the macOS Mojave 10.14 beta. Upon trying to install Pallet, it tried to install its dependency MacPorts_Framework:

Error: Failed to destroot MacPorts_Framework: command execution failed

Error: Processing of port Pallet failed

Notice that it failed during the destroot stage. This is reflected in the log file which I've attached. My situation is a bit strange, since both Xcode 9.4.1 and Xcode 10 beta 6 are installed. I selected Xcode 10 via ​this Ruby gem. Specifically, I ran:

$ xcversion select 10.0

Obviously, this is a non-standard configuration so it is understandable if this could cause issues. Anyway, the log file is below. I tried to see what really happened, but I can't make much sense of it. I suppose the issue is mainly that:

1. I'm on a beta and
2. The Xcode situation is weird, as explained above.

FYI, here is the OS version:

ProductName:	Mac OS X
ProductVersion:	10.14
BuildVersion:	18A377a

It's known that MacPorts_Framework does not build on recent systems; see #45835. The log you've attached here looks like a different error. Certainly, the log says there is an error which you should report to Apple's bug reporter; you should do that. I don't know if that's the only new problem though.

Also keep in mind that you shouldn't discuss prerelease Apple software in a public place like this; see wiki:FAQ#prerelease.

Thanks, I'll try that and see what happens. I didn't see that error the first time I looked at the log.

Also keep in mind that you shouldn't discuss prerelease Apple software in a public place like this; see wiki:FAQ#prerelease.

Sorry, I forgot about this rule. I'll try to be careful about it in the future. Fortunately, it's quite unlikely that Apple will care, let alone notice this.

I think this is #57137.
