[maemo-developers] getting qt-ruby working on maemo

[From: Martin DeMello]

I have installed kaspernj's optified ruby packages from here:
http://talk.maemo.org/showthread.php?t=39797

I then compiled the qtbindings gem on the scratchbox, as follows:

 apt-get install cmake
 apt-get install libqt4-dev
 gem install rake
 gem install qtbindings
 cd /opt/ruby/lib/ruby/gems/1.8/gems/qtbindings-4.6.3.0/
 rake gemnative

which all worked, generating a qtbindings-4.6.3.0-arm-linux.gem which
installed happily enough on the n900. However, running it fails:

LoadError: libsmokeqtcore.so.3: cannot open shared object file: No
such file or directory -
/opt/ruby/lib/ruby/gems/1.8/gems/qtbindings-4.6.3.0-arm-linux/lib/1.8/qtruby4.so

What's the simplest way to get libsmokeqtcore.so.3?
