M4 fails on Ventura due to depending on /usr/lib/libiconv.2.dylib instead of /opt/local version

/opt/local/bin/gm4 --version

what system are you running this on?

[asvitkine]

I'm confused by the dyld error since running otool on the binary doesn't show a dependency to the /usr/lib file:

$ otool -L /opt/local/bin/gm4
/opt/local/bin/gm4:
	/opt/local/lib/libiconv.2.dylib (compatibility version 9.0.0, current version 9.1.0)
	/opt/local/lib/libintl.8.dylib (compatibility version 11.0.0, current version 11.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1953.1.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1319.0.0)

Hmm, I uninstalled all my ports and reinstalled using ​https://stackoverflow.com/a/27784713/14596701 and I am not seeing this anymore.

I think we'll close this ticket then as we'll never sort anything out with this now.

Pls reopen if you get a consistent failure again.

The original error looks like the kind of thing you get if you have DYLD_LIBRARY_PATH set (or possibly some other DYLD_* variables). Don't use /usr/bin/env to check for this BTW, as it is a SIP-protected binary and will not see any DYLD_* environment variables.
