[swift-users] Swift linux repl can't import

From https://bugs.swift.org/browse/SR-3648, the work-around seems to be passing -I /path/to/extracted/usr/lib/swift/clang/include when invoking swift (credit Lukas and others, SR-3794 is more active)
So, ex. `swift -I ~/a-swift/usr/lib/swift/clang/include/`
Fortunately, the issue has only come up for me in the REPL. `swift build` works fine: I can build packages without an awkward -Xswiftc…
I wonder if the issue has anything to do with the clang-builtin-headers install component? (Maybe swiftc/something gets hardcoded with a path somewhere?)
Would be interested in learning more about install options, toolchains, and the build! I’ve been wanting to track down for a while now, how does --install-prefix affect the build? I’ve been relying on install_destdir to get a swift...
