So I'm trying to install this gem but hitting an error. https://github.com/cgore/ruby-btce The actual README says to do a gem install, so I guess I didn't need to clone the git repo? Anyway, I had to install Ruby before doing this and that's all I've installed so far, so I guess I may be missing some other dependencies to install this gem? Error I am getting when attempting a "gem install btce" is:
ERROR: Error installing btce: eRROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:13:in <main>
Considering it's a gem install and I guess it would be the equivalent of installing something from another package manager, it means that nothing already on my existing file system is required (such as a file... that it appears to be missing).
So my next assumption would be a missing dependency. But is there a way to find what it could be when the error message doesn't say what is missing?
