modifica: [FISSO] Il problema era che l'avevo già installato, ma non lo sapevo, e ho provato ad installarlo dal sorgente. Questo ha creato due versioni e la gemma non sapeva quale usare. Ho riparato andando alla fonte scaricato e funzionanteLa gemma di RMagick non riesce ad essere installata su Debian Stable
sudo make uninstall
Poi corsi gem install nuovo RMagick e ha funzionato!
[problema originale]
Sto cercando di installare la gemma RMagick come in this railscast. Ecco un frammento di quello che ho messo nel mio Gemfile:
gem 'rmagick'
gem 'carrierwave'
E quando corro bundle install ottengo il seguente output:

penso Ho esaurito tutte le informazioni su come risolvere questo errore tramite google/stackoverflow. Ho già provato a installare i pacchetti di sviluppo e così via. Non so da dove andare. Qualsiasi aiuto molto apprezzato.
Conferma. Funziona anche con Debian 7.8! – Stradivari
e 8.8 come pure – Nathan
e debian 9 (stretch) - apt-get install libmagickwand-dev offre 60 dipendenze, ma gem installazione rmagick funziona! – iheggie
