When I uninstall a gem which has bin scripts and installed with format-executable option, the scripts remain after the gem uninstallation.

# install the trunk ruby with program suffix configuration.

$ ../ruby/configure --prefix=/usr/local --program-suffix=-r29806 --srcdir=../ruby --enable-shared --with-opt-dir=/opt/local
$ make
$ sudo make install

This is because rubygems/uninstaller.rb references Gem::Installer.exec_format without requiring rubygems/installer.rb.

Try again without --format-executable...

• lib/rubygems/uninstaller.rb: Add missing require and update messaging to avoid confusion with uninstall --format-executable. [Ruby 1.9 - Bug #4062]

[drbrain (Eric Hodel)]

The feature was only partially implemented in RubyGems 1.8. It was missing a require and had confusing messaging.
