win7 rails aptana studio 3 rmagick cannot start debug server

Hi,

i've set up my win7 64bit box for ROR development. i got every thing installed but now i'm stuck at debugging my application. i installed aptana studio 3 and tried to run 'debug server', the following errors returned.

Fast Debugger (ruby-debug-ide 0.4.16, ruby-debug-base 0.10.4) listens on 127.0.0.1:55255 C:/Ruby/work/whistle/config/../config/preinitializer.rb:8 C:/Ruby/work/whistle/config/boot.rb:28:in load' C:/Ruby/work/whistle/config/boot.rb:28:inpreinitialize' C:/Ruby/work/whistle/config/boot.rb:10:in boot!'

Install it with gem install bundler.

i'm pretty sure it's related to rmagick, but i don't know what i've done wrong. i use bundler for gem management. if i comment the "gem "rmagick", "2.12.0"" line in gemfile, i can successfully start the server by running "ruby script/server". i just don't know what's wrong with the debug.

can anybody tell me what is going wrong? how can i fix it? thx.
