Heroku Toolbelt Issues on osx 10.5.8 -

so beginning work heroku (on old mbp running osx 10.5.8) , having issues toolbelt. installation finished no errors, unable run of heroku commands terminal. running ruby 1.9.3 through rvm (if helps). 'which heroku' command gives:

$ heroku /usr/bin/heroku 

all other commands beginning 'heroku' return following error (using login example):

$ heroku login dyld: unknown required load command 0x80000022 trace/bpt trap 

if shed light on me, appreciated. let me know if leaving out info. thanks!

edit: also, did re-install older version of git osx 10.5.8 suggested many forums , here https://github.com/heroku/heroku/issues/324 (i know specific post pointed @ git breaking, seemed general answer on forums had remotely related problem)

seems simple fix. heroku gem never installed toolbelt (i assume should have been?). fix was:

$ gem install heroku
