fails to build beta on openbsd6.6/amd64

[tera-torn]

tried on two different openbsd6.6/amd64 boxes - same errors. errors don't really make sense to me and google isn't much help.

I would really appreciate any help understanding the problem or figuring out a workaround. Thanks for making build-rust - I really wish it worked for me, and would love to help fix this (I know it may not be the script's fault.. probably isn't.. but we'll see)

From build.log:

Mon Dec  9 23:40:10 CST 2019: info: required stage0:
        date: 2019-11-07
        rustc: 1.39.0

you are trying to build 1.40.0-beta.5 with 1.38.0. It isn't supported by rust itself. For building 1.40.0 you need to first have 1.39.0.

Regarding OpenBSD itself, 6.6 doesn't have 1.39.0 in ports (and will not). Only -current will have it. Eventually, you could try to build lang/rust from current on 6.6 (it should work, even if it is an unsupported configuration).

Good to know. I'll try to build some intermediate compilers first. Thanks!
