tiff@4.3.0_0+universal: Failed to destroot tiff, "libtiff-4.pc differs"

[JDLH (Jim DeLaHunt)]

Attempting to install tiff@4.3.0_0+universal on an arm64 machine running macOS 12.3 Monterey fails during destroot because "libtiff-4.pc differs".

port uninstall tiff followed by port install tiff +universal is not effective.

In the same environment, installing tiff@4.3.0_0 without +universal succeeds.

I have attached the main.log file. The interesting part appears to be:

Why am I installing tiff +universal? I'm not sure. I am migrating from an older machine, which runs MacPorts on macOS 10.14.6 Mojave on x86_64. I think multiple other ports are +universal for some reason, and they depend on tiff, so MacPorts tries to install tiff +universal.

Additionally, attempting to install tiff+universal as second time, after a previous failure, fails during destroot with a different message, "file already exists". But doing port clean restores us to the first error. I think the second error is less important, and so out of scope for this ticket.
