vim-gtk and vim-gnome both have libruby1.9.1 as a package dependency (in trusty), which in turn depends on ruby1.9.1 and I fear doing sudo apt-get install vim-gtk will cause commands such as irb and rails to invoke 1.9.1 stuff. What is a good way to install gvim without tampering with my hard-won ruby setup?

EDIT:

As advised by A.B. in comment below, I checked out "I installed a program by getting its source code, and then running sudo make install; how to make apt-get know about it?"

As suggested in the answer to that question, i tried sudo checkinstall -D make install in the directory containing the Makefile for Ruby 2.2.3. Checkinstall informs me that:

**********************************************************************

 Done. The new package has been installed and saved to

 /home/xxxx/Downloads/software/ruby-2.2.3/ruby_2.2.3-1_amd64.deb

 You can remove it from your system anytime using: 

      dpkg -r ruby

**********************************************************************

This is a nice amenity, but apparently doesn't get libruby, ruby, etc. into the already-satisfied-dependencies list:

Is it significant that 1.9.1 is part of the package name itself (rather than a version number that applies to the package) in the case of libruby-1.9.1 and ruby1.9.1? It also says the package ruby will be upgraded. I fear it will be downgraded. I also tried sudo dpkg -i ruby_2.2.3-1_amd64.deb (the debfile having been created by checkinstall) followed by trying to install vim-gtk.

FURTHER EDIT:

Tried adding the alternative PPA per @muru's suggestion. Then sudo apt-get install vim-gtk, which pulls in ruby1.9.1 as a dependency, but ruby -v shows ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux], so I think I'm probably good to go.

Seems apt-get is still offering ruby1.9.1 et al.
