Hi Carlo,

I'm using gem and bundle to install software. And is at this point where
I'm lost.
There's no extension directory and no extconf.rb file.

I could identify a Rakefile, and a Gemfile.
Tried setting up somethin like:
export CC=arm-linux-gcc, and so
export PATH=/path/to/cross-compiled/ruby/bin:$PATH
then gem install

But i'm getting something:
/dest/bin/gem: line 8: require: command not found
/dest/bin/gem: line 9: require: command not found
/dest/bin/gem: line 10: require: command not found
dest/bin/gem: line 12: required_version: command not found
[...]

I think I'm loosing something.. can you help me please?

thanks!
