[Rock-dev] Ruby error building in base/types_ruby

[Javier Hidalgo Carrió]

Hello rocks,

I upgraded to Ubuntu 11.04
I have ruby 1.8:
     ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

and
     gem --version
         1.3.7

But when building base/types_ruby    I get the following error:

setting up Ruby package base/types_ruby
Build failed
base/types_ruby: failed in post-install phase
     'rake default' returned status 1
     see 
/home/jhidalgocarrio/CUSLAM/cuslam-dev/install/log/base/types_ruby-post-install.log 
for details
     last 10 lines are:

     
/home/jhidalgocarrio/CUSLAM/cuslam-dev/.gems/gems/rice-1.4.3/ruby/lib/mkmf-rice.rb:79:in

         from extconf.rb:6

It seem that cannot find ruby or Rubygems
Any idea?

Thanks,

Javier.
