Hi,
Julia is not installing under MacPorts.
There’s an open ticket there for some time, https://trac.macports.org/ticket/57452
but there is no progress.
I am really interested in Julia and I am wondering if nobody else encountered this…
I’m not quite sure what you’re linking to - there are official binaries for mac available here. Note that only binaries distributed via julialang.org or built from source using the github repository are supported.
The error message you’ve posted indicates a problem with the third party distribution.
I have to admit I’ve never heard of anyone ever using Julia via MacPorts. I’ve run Julia on OSX for several years now and have always just installed it via the .dmg files available at https://julialang.org/downloads/ . I would suggest just doing that as well.
