Bad error messages when dependencies are missing

[stzokev]

If I don't have innoextract I get the
/var/lib/gems/2.3.0/gems/cocaine-0.5.8/lib/cocaine/command_line.rb:82:in `run': Cocaine::CommandNotFoundError (Cocaine::CommandNotFoundError)

which others have reported before. So apparently it is not optional as indicated in the instructions. Or if it is optional in some cases, a clarification might be needed.

Great tool otherwise! Thanks for your hard work!

it's optional unless it's actually required for extraction. i should probably catch these errors and print a more helpful error message

[coderobe]

Specifically, though, it will tell you

checking for innoextract... no
Install 'innoextract' on your system (required for Inno Installers)

Yes, but it gives similar error messages for all dependencies, and half of them are marked as optional. Knowing that, I just ignore these messages.
