Bug #3564: 'gem uninstall' doesn't remove executables which were installed with --format-executable option
http://redmine.ruby-lang.org/issues/show/3564

Author: Kenta Murata
Status: Open, Priority: Normal
Category: lib, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-07-11 revision 28613) [x86_64-darwin10.4.0]

'gem uninstall' command doesn't remove executables installed with --format-executable option, but ones installed without the option.
The command, unfortunately, doesn't allow us the option so we are obliged to remove the executables manually.

Operation Log:
