Finder in OS X seems to be retarded at finding hidden files and folders. In my case, I wanted to recursively remove all .svn folders from a directory. To do this, it's command line to the rescue:

If you've tried installing the rjb 1.1.x gem on Mac OS X Leopard, you will probably end up with an error like:


lipo: can't open input file: /var/tmp//ccpyNy8b.out (No such file or directory)
make: *** [load.o] Error 1


In order to get around this you have to run the following commands:


sudo su -
export JAVA_HOME='/System/Library/Frameworks/JavaVM.framework/Home'
gem install rjb
