Among other issues, this is using a bundled binary of libXm which is not built for arm64.

[vidakris]

Using the openmotif port instead and linking it at compiling could be a workaround for that, but that also gives a segfault:

$ ./xephem

In 4ce46e2e0925ede76d16d4c4e42038a615171ebe/macports-ports (master):

xephem: fix build on Ventura

add dep on groff if needed

supported archs are i386 / x86_64 / ppc based on bundled library
this may be fixable at some point in the future

add build arch
