Could not find rake-0.8.7 in any of the sources

Rails
1

After upgrading my server to:
Ubuntu server 10.10
Ruby 1.9.2
Rails 3.0.1
Passenger 3.0.0
rake is unable to find itself:

rake -T
Could not find rake-0.8.7 in any of the sources
Try running bundle install.

but gem list and ‘bundle list’ shows that rake-0.8.7 is installed!

When loading the webapp in the browser:
Could not find rake-0.8.7 in any of the sources (Bundler::GemNotFound)

Ruby 1.8.7 is also installed on this server, but the following
symbolic links have been created in ‘/usr/bin’:
ln -s ruby1.9.1 ruby
ln -s ri1.9.1 ri
ln -s rdoc1.9.1 rdoc
ln -s gem1.9.1 gem
ln -s irb1.9.1 irb
ln -s rake1.9.1 rake

/var/lib/gems/1.9.1/bin is in the $PATH.

Running rake in my home folder, with a minimal Rakefile, works!

Any suggestions?

Solved!

In the top of ‘/usr/bin/bundle’ it said:
#!/usr/bin/ruby1.8

I replaced it with:
#!/usr/bin/env ruby

now bundler and rake works again.
