I'm having trouble installing because there is: no J no --strip-components on OpenBSD 7.4

Would you use xzcat gettext-0.21.tar.xz | tar xf - instead?

I tried to make the changes but I don't know rust and got stuck. sorry. Error: no field `stdout` on type `Result<Child, std::io::Error>`

Thanks! Windows also has problems with tar, so we'll ship an unpacked tarball instead. I hope to push it out next week.

I think this is an easy fix. Can this changed?
