Comment (by r.keoni@…):

 I did a quick and unsuccessful attempt to build using the beta channel
 binaries as stage0.
 That gets past the configure hang but would require further patching of
 the 1.11 sources, on the very weak assumption the #[feature] tags are
 redundant when using that stage0 binary.
 Possibly worth trying using the 1.11.0 binary eventually intended for use
 in building the release 1.12?

 Relevant changes to Portfile that I tried:
 {{{
 set stage0(date)        2016-08-17
 set stage0(version)     beta
 }}}

 {{{
     default {checksums-append   ${stage0(distfile)} \
                             rmd160
 c30a0c2e92bb26117270e622b0918eade050452c \
                             sha256
 c268352695b155ff24fe3d65de163a87d32e1371698562d89461fcef6c65b438}
 }}}


 Example error in the build:
 {{{
 :info:build error[E0554]: #[feature] may not be used on the beta release
 channel
 :info:build   --> src/libcore/lib.rs:64:1
 :info:build    |
 :info:build 64 | #![feature(allow_internal_unstable)]
 :info:build    | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 :info:build
 }}}
