private method `equal?' called for {}:Hash

I have two servers in production. Same installation, same ruby version, same rails, deployed using capistrano.

Suddendly one server gives this error: private method `equal?' called for {}:Hash even if I start the console:

/var/www/reputation/releases/20081006154941/vendor/rails/activerecord/ lib/../../activesupport/lib/active_support/core_ext/class/ inheritable_attributes.rb:127:in `inherited':NoMethodError: private method `equal?' called for {}:Hash /var/www/reputation/releases/20081006154941/vendor/rails/activerecord/ lib/../../activesupport/lib/active_support/core_ext/class/ inheritable_attributes.rb:127:in `inherited':NoMethodError: private method `equal?' called for {}:Hash /var/www/reputation/releases/20081006154941/vendor/rails/activerecord/ lib/../../activesupport/lib/active_support/core_ext/class/ inheritable_attributes.rb:127:in `inherited_without_layout':NoMethodError: private method `equal?' called for #<Hash:0xb76c5978>

What can it be ?

I have deleted, rebooted and redeployed from scratch but the error persists.

Hi,

Hi,

it appears it was Debian specific issue in my problem.

Debian's libgsl-ruby library automatically included GSL namespace when library was included. I had to edit gsl.rb file and comment out "include GSL" to prevent conflict with activesupport.
