[DRE-maint] Bug#746470: rubygems-integration: fails to read arch-specific gemspecs for ruby2.1

[Cédric Boutillier]

Package: rubygems-integration
Version: 1.6
Severity: important

Hi,

Running gem2.1 list does not show any gemspec for arch specific Ruby
libraries installed as a Debian package, despite the fact that the
gemspec are installed in /usr/share/rubygems-integration/2.1.

The problem is that rubygems-integration makes the gem command look in 
/usr/share/rubygems-integration/2.1.0 instead, because 2.1.0 is the API
version of ruby2.1, as indicated by Gem::ConfigMap[:ruby_version]
A workaround is to installed by rubygems-integration for 2.0 by adding a
symling 2.0.0 -> 2.0.

Probably one needs to fix the path for /usr/share/rubygems-integration
or fix gem2deb to install in /usr/share/rubygems-integration/2.1.0.

Cheers,

Cédric
