My rake is broken - "no such file to load..."

Hey folks

After doing an update from our svn server, rake is no longer working for
me, though it’s fine for my team-mates. I get this error:

no such file to load – spec/rake/spectask
/home/max/work/e_learning_resource/trunk/Rakefile:10:in `require’

when i try to do any rake task. The file it mentions looks like this,
with line 10 being the last line:

#Rakefile

Add your own tasks in files placed in lib/tasks ending in .rake,

for example lib/tasks/capistrano.rake, and they will automatically

be available to Rake.

require(File.join(File.dirname(FILE), ‘config’, ‘boot’))

require ‘rake’
require ‘rake/testtask’
require ‘rake/rdoctask’

require ‘tasks/rails’

Can anyone help?
thanks, max

I figured this out - it was because i’d updated rubygems, which was now
looking in a different folder for the gems than the one they were living
in. So, my gems were all missing, effectively.
