Warning: The install command is a part of the legacy v1 style of cabal usage.

Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.

Configuring hruby-0.3.8...
Warning: Could not find the ruby library. Ensure that it is present on your
system (on Debian/Ubuntu, make sure you installed the ruby1.8-dev package).
If you know it to be installed, please install hruby in the following way
(example for nix):

$ cabal install hruby -p --configure-option="--rubyversion=19 --rubylib=ruby
--rubyinc=/nix/store/v0w14mdpcy9c0qwvhqa7154qsv53ifqn-ruby-1.9.3-p484/include/ruby-1.9.1
--rubyinc=/nix/store/v0w14mdpcy9c0qwvhqa7154qsv53ifqn-ruby-1.9.3-p484/include/ruby-1.9.1/x86_64-linux'
--extra-lib-dirs=$HOME/.nix-profile/lib/"

--rubylib : Should be the name of the library passed to the linker (ruby for
libruby.so).
--rubyinc : There can be several instances of this flag. Should be the path of
the various ruby header files.
--rubyversion : Mandatory for ruby 2.0 and 2.1, should have the values 20 or
21.
setup: Missing dependency on a foreign library:
* Missing (or bad) header file: ruby.h
* Missing (or bad) C library: ruby
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the
library file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
