make: g++: Command not found 
make: *** [emwin.o] Error 127 

il a mentionné que g ++ était absent, donc je l'ai fait:

sudo apt-get install g++ 

puis couru:

sudo gem install thin 

et il a travaillé

aussi, je ne suis pas sûr si elle peut avoir rien à voir avec cette installation, mais comme il est un parfois précaution, installer 64 bits, j'installer les 32 libs:

sudo apt-get install ia32libs 

mais j'Installez toujours le 32libs dès que je installer un nouveau serveur 64 bits
