As the title suggests, I am trying to compile Julia (v0.6.2) from source (to enable MKL support)  
Unfortunately, I get the following error:

```julia
curl: (7) Failed to connect to ftp.csx.cam.ac.uk port 443:Connection refused

```

Did anyone encounter something similar?

What OS are you using?

Tamas\_Papp asks the correct question. [ftp.csx.cam.ac.uk](http://ftp.csx.cam.ac.uk) seems to be down. I suspect this is a rather old machine, which is no longer in use.

Ay caramba… over on a mailing list not a million miles away I was arguing that in the context of offering Redhat, SuSE or Ubuntu to users who are used to Ubuntu that ‘linux is linux is linux’.  
And here I am, hoist by my own petard. Karma is a bitch etc.

Snir, you of course are corect to reply linux. You could get the ‘flavour’ by cat /etc/_elease_  
and the kernel version by uname -r

I got exactly the same error a couple of days ago.  
I’m using Debian GNU/Linux 9 (stretch).

Kristoffer’s answer is correct — this is simply an outdated URL in our build system. It’s been backported and will be fixed in any subsequent 0.6.x patch releases, but in the meantime you can download the _full_ tarball which already bundles these dependencies for you:

[https://github.com/JuliaLang/julia/releases/download/v0.6.2/julia-0.6.2-full.tar.gz](https://github.com/JuliaLang/julia/releases/download/v0.6.2/julia-0.6.2-full.tar.gz)

As a dirty workaround – you can manually apply the following change:

[https://github.com/bribroder/julia/commit/4b5cb5d5296cd76eda0cef17d48b8f2ee1cc2745](https://github.com/bribroder/julia/commit/4b5cb5d5296cd76eda0cef17d48b8f2ee1cc2745)

worked for me.
