I ran my test suite with 'rspec', everything passed, then I ran 'bundle clean --force' which cleaned up my RVM gemset (issolated from system gems). Then I ran test suite again, and it said "no such command: rspec". The binary file for rspec was no longer there. Does 'bundle clean' remove the bin file of the latest gem?
#1532: add failing test case on non "bin/" bindir
#1532: use Gem.bindir and not spec.bindir for bundle clean
