Bug Description
== Jekyll package once installed still requiring classifier gem
after install this error message
> jekyll -v
Dependency Error: Yikes! It looks like you don't have classifier or one of its dependencies installed. In order to use Jekyll as currently contfigured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- stemmer' If you run into trouble, you can find helpful resources at http://

To get it to work I had to install the ruby package 'classifier' with gem ('sudo gem install classifier') which required ruby headers ('sudo apt install ruby-dev')
Attacched is a log file with an example session.
Overall Issue and Reproduction
-------
> raspbian jessie lite
> apt update, apt upgrade, all up to date
> install jekyll with 'sudo apt install jekyll'
> jekyll does not start, displays need for 'classifier'
> installed manually the classifier with gem 'sudo gem install classifier'
> jekyll works

Workaround
----------
In order to progress with my use I have manually installed gem 'classifier'.
> jekyll -v
Dependency Error: Yikes! It looks like you don't have classifier or one .....
....
> sudo apt install ruby-dev
> sudo gem install classifier
> jekyll -v
jekyll 2.2.0
Reportbug - after workaround
-------
Same as before workaround. Checked with diff.
Humble Analysis
---------------
The package ruby-classifier is installed. Although Jekyll cannot access it via ruby.
Is it maybe, in this arm package version, not 'exporting' its functionality system-wise
as when installed with gem ?
Unfortunately I have no ruby knowledge to further speculate.
I have tested on an fresh jessie installation, up-to-date, on a PC x64 the same day. And
the jekyll installation worked out of the box, it found 'classifier', so the issue might lay
in this architecture version of the packages.
Cheers

Available for any further info/test !
Wish all the team an outstanding day,

Reading the error carefully it looks like the problem is not classifier itself but one of it's dependencies, "stemmer" which seems to be provided by the package ruby-fast-stemmer.
Afaict there are a few aspects to this
1. Some ruby gems need a native-code component. This component must be built for the right version of ruby.
2. we don't have any mechanism for automatically removing packages that are removed from Debian (I possiblly should implement one but it's more complex than it first appears and i've never got around to figuring out the details) so there is still a libruby1.8 package present.
3. Debian's dependency system doesn't adequately express the complexities of the dependency situation.
The result of this is that the ruby-fast-stemmer package in raspbian jessie is built against the wrong version of ruby but everything looks fine to dependency checking tools.
