transmission @4.0.6: Transmission.app fails on 16.0: invalid iconv dylib

[wwalexander (William Alexander)]

I'm getting the following error when trying to run Transmission after installing on macOS Sequoia 15.0, Xcode 16, build version 16A242d.

Termination Reason:    Namespace DYLD, Code 1 Library missing
Library not loaded: /opt/local/lib/libiconv.2.dylib
Referenced from: <D9ADBC76-D4BB-39E5-BE4E-1DF90E05ACB5> /Applications/MacPorts/Transmission.app/Contents/MacOS/Transmission
Reason: tried: '/opt/local/lib/libiconv.2.dylib' (code signature in <716EAB0F-F44E-3268-979E-0AE142AA7709> '/opt/local/lib/libiconv.2.dylib' not valid for use in process: mapping process and mapped file (non-platform) have different Team IDs), '/System/Volumes/Preboot/Cryptexes/OS/opt/local/lib/libiconv.2.dylib' (no such file), '/opt/local/lib/libiconv.2.dylib' (code signature in <716EAB0F-F44E-3268-979E-0AE142AA7709> '/opt/local/lib/libiconv.2.dylib' not valid for use in process: mapping process and mapped file (non-platform) have different Team IDs)

I do have the Command Line Tools uninstalled as described in ticket:70750; it seems plausible this bug could be related so apologies if this is an upstream issue or unique to my machine.

It seems that macOS also provides its own copy of libiconv, so I'm guessing that this is in fact due to the Sequoia CLTs mitigation and this ticket should probably just be closed.

But maybe it's possible to get the build working regardless of CLTs; I'm not familiar enough with the intricacies of xcodebuild to be able to offer many insights.
