ncursesw universal build x86_64 fails on 32 bit platforms

[mcl_guard-netmail@…]

The port file for ncursesw assumes a 64 bit platform when determining what archs require cross compiling turned on. This results in an error trying build the universal variant on a 32 bit machine.

Why do you want to build for 64-bit on a 32-bit machine?

Please remember to cc the maintainer.

This is one of the drawbacks of using muniversal.

[mcl_guard-netmail@…]

The idea here is to be able link apps with with both 32bit and 64 bit code against the libraries. I am trying to build the universal variant for both 64 and 32 bit. Yes just 64 bit would not make much sense.
