Comment (by ryandesign):

 Replying to [comment:3 Gcenx]:
 > Replying to [comment:2 ryandesign]:

 is that the former use case-sensitive file systems. Are all of your paths
 capitalized correctly?
 >
 > That's the strange part all the paths are correct, I've attached a
 screenshot of this being installed locally where it shows as
 `libMoltenVK.A`

 The screenshot shows what got installed into the destroot and from there
 was packaged into the port's binary archive, not what existed in the
 original distfile. Certainly if you tell the OS to copy a file and the
 case you use is not correct but your file system is case insensitive, then
 the copy will succeed and the copied file will have the new ("incorrect")
 case:

 {{{
 % mkdir foo bar
 % touch foo/a
 % cp foo/A bar
 % ls bar
 A
 }}}

 > The only `Big Sur (arm64)` buildbot worked but shows this as
 `/opt/local/Library/Frameworks/MoltenVK.xcframework/macos-
 arm64_x86_64/libMoltenVK.a`, so should I change the Portfile to instead
 just expect that?

 It is libMoltenVK.a, with a lowercase "a" (as all static libraries are):
