Did you build rugged from source? Can you post the output of mkmf.log? Please put it into a gist and put the link to the gist here, as the mkmf.log output can be quite verbose.

The mkmf.log files for rugged-0.23.0b1, rugged-0.23.0b2 and rugged-0.22.2 can be found here. On all versions ssh support was not detected.

@carlosmn Looks like CMake can't find libssh2 😞 Any idea what might be causing this?

[arthurschreiber]

Okay, I just checked on my machine, and it works fine on my machine:

$ pkg-config --libs libssh2
-L/usr/local/Cellar/libssh2/1.5.0/lib -lssh2

From my mkmf.log:

-- checking for module 'libssh2'
--   found libssh2, version 1.5.0

My first guess would be that your login shell has either a different pkg-config from the one which can be found on the system, or that you have set a search path there which the CMake-called pkg-config wouldn't see.

One way to make sure that libssh2 can be found using the "normal" paths is to run brew link libssh2 which will make sure to create the right symlinks.

@carlosmn thanks for the hint about maybe using a different pkg-config. I got it working by doing a brew uninstall pkg-config && brew install pkg-config.
