Hi Arun,

Have you fixed the problem? I got a similar problem with the following
setup. Can you share with me on how to fix it? Thanks.

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.

gem. 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.
