Can't run conrod on OSX 10.9.5

[caillette]

Hi all, I can't build Conrod on Mac OS X 10.9.5 (Intel Core i7).
This is what happens:

Could not compile `conrod`.

To learn more, run the command again with --verbose.   

I'm aware of a problem with Freetype. I'm using this workaround:

$ cat ~/.cargo/config
[target.x86_64-apple-darwin.freetype]
rustc-link-lib = [ "freetype:dylib" ]

The workaround worked for building and running Piston "getting-started". But the "-l" "freetype:dylib" in the error message means the directive has no effect when we build Conrod.

Any idea?

Hey @caillette, sorry about the late reply!

The graphics backend of the piston_window crate that we use for the examples just recently changed over to use rusttype instead of freetype-rs. We still need to update the version for each of conrod's piston dependencies to take advantage of this, but hopefully we'll get around to this very soon.

A related comment.

The Freetype crate has been the cause of the majority of our users' issues (I think it's the only non-Rust code that conrod depends on) so hopefully the change will fix your issues, along with a lot of others'!

[caillette]

OK that's good news, then. FreeType installation happened to be painful.
