[Rock-dev] [Rock-users] Installing rock (master) on Ubuntu 14.04 - Ruby1.9.1 error?

I had the same problem twice by accident:

source a existing installation  (old) and try to boostratp a new one
or
delete everything of your installation "cd dev; rm -fr *" (which keeps 
the .gems there) and start the bootstrap.
I assume ruby is struggling here with different versions when the 
installed gem has a rice-extension.

However it is a ruby problem and old gem's should not exist for rock, we 
can think about a sanity check somehow (but i don't know where).

But in rauls case the core-problem is that he has installed the gems 
system-wide...

Best,
Matthias
