Bah, ok, I thought that if a UB existed, that the CPU had to support it. So the OS knows how to ignore the bits of a binary that have architecture specific builds in it even if the hardware itself can't support it? Thats interesting to learn. So in theory, you could see `file` return PPC as an option, even if it were obviously as in this case, Intel?
I never would have thought this to be the case, and thought it more like trying to run a classic app on a new machine of today.

That is the command I wanted then, and that explains it:
What is getting me, is this should be 64 capable, according to system_profiler:
Model Name: Mac mini
Model Identifier: Macmini1,1
Processor Name: Intel Core Duo
Processor Speed: 1.66 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MM11.0055.B08
I thought only the Core Solo's were not 64 bit capable, and anything Core 2 Duo were? Or is this the difference in a Core Duo and a Core _2_ Duo?

Clean ncursesw, then try installing ncursesw +universal again to get the real error message, then show us that.
I did that too. I finally just took off the +universal, which means I had to clean again, but then things seemingly went along fine.
Someone on #macports said this was a bug, which is why I came here. I am guessing this is not a bug, and I was doing this wrong, which was trying to build universal on a arch that does not support it.
Hoever, would it not be a good idea to save the user from this mistake? If hw.cpu64bit_capable returns 0, then either the +universal could be ignored, which could be ambiguous to the user, with them thinking a UB was made, or, MP could exit out with an error: "Sorry, your machine does not support building as +universal".
I managed to get it all running, another MAMP install successfully working, hooray!
Thanks for the pointers.
