[DRE-maint] Bug#860512: Bug#860512: ruby-ronn: fails on m68k (no fast_xs)

[Christian Hofstaedtler]

Hi,

>   ronn --roff debian/telegram-desktop.1.md
>   /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- fast_xs (LoadError)

This usually means the ruby-fast-xs package is missing or broken or
the search paths are incorrect.

Please provide:
 - ruby -e 'puts RbConfig::CONFIG'
 - strace -eopen ronn --roff debian/telegram-desktop.1.md
 - installed versions of ruby* (esp. ruby-hpricot, ruby-fast-xs,
   ronn)

PS: ronn hasn't seen any development since 2013. It's advisable to
migrate off it.

Cheers,
C.
