Unable to run calabash-ios + rspec tests with the updated Gem versions -

i created few calabash-ios tests using rspec in rubymine ide on mac mini worked great;

however moved imac , had configure , install ruby , necessary gems. however, time not execute tests due following error , i'm stuck. (copied error message below)

best guess related difference in version of gems on both machines. did version comparison in detail, observed quite few differences.. listing here ones think relevant error: (and unfortunately, not able install older version of gems (on imac) not exists anymore, instead updated versions)

listed tge versions in form of gem name = version on oldmachine && version on newmachine

cfpropertylist = 2.2.0 && 2.2.1

httpclient = 2.3.3 && 2.3.4.1

rspec = 2.14.1, 2.9.0.rc2 && 2.14.1

rspec-core = 2.14.4, 2.14.3, 2.9.0.rc2 && 2.14.5

rspec-expectations = 2.14.1, 2.14.0, 2.9.0.rc2 && 2.14.2

rspec-mocks = 2.14.3, 2.14.2, 2.14.1,2.9.0.rc2 && 2.14.3

rubygems-update = 2.0.6, 2.0.5 && 2.0.7

has else come across issue updated versions of gems?

please share pointers me resolve earliest possible. there way move old version of gems , check if tests work correctly?

or is there else think , suggest me try make tests run??

i confirmed firewall off

the error occurs when attempted launch simulator under 'before' block in _spec.rb file : @launcher = calabash::cucumber::launcher.new @launcher.new
