Problem resolving dependencies when building on Travis with CocoaPods 1.0.0.beta.6

NOTE:
I'm not sure if this is a Travis issue or a CocoaPods issue, since I can't reproduce this locally but only on Travis. However - since what Travis does when failing is running pod install and it seems to be a very clear problem in dependency mechanism I doubt it's not related to CocoaPods itself.
I managed to reproduce the problem on this repo: https://github.com/joytunes/cocoapods-bug
And problem can be seen in Travis build's log: https://travis-ci.org/joytunes/cocoapods-bug/builds/122806124

What did you do?

Trying to run a Travis build of a very straightforward pod with cocoapods 1.0.0.beta.6, after running pod update locally and committing the Podfile.lock.
In the example it has only DTCoreText as a dependency, although I saw this happen with other pods as well.

What did you expected to happen?

Travis would easily manage to run pod install

What happened instead?

Travis writes this error which doesn't make sense (dependencies aren't conflicting and 1.7.10 seems like a very legit version in the Specs repo):

[!] Unable to satisfy the following requirements:
- `DTFoundation/Core (= 1.7.10)` required by `Podfile.lock`
- `DTFoundation/Core (~> 1.7.5)` required by `DTCoreText (1.6.17)`

None of the spec sources contain a spec satisfying the `DTFoundation/Core (= 1.7.10)` dependency.
You have either; mistyped the name or version, not added the source repo that hosts the Podspec to your Podfile, or not got the latest versions of your source repos.

Podfile

source 'https://github.com/CocoaPods/Specs.git'
project 'cocoapods-bug.xcodeproj'

target 'cocoapods-bug' do
    pod 'DTCoreText'
end

A workaround would be to put
pod 'DTFoundation/Core' '=1.7.5'
in the Podfile, but this is of course a lousy workaround.

Maybe you need to run pod install with --repo-update if Travis isn't providing an up-to-date specs repository and you're not checking in your Pods directory.

Yep this solved it. Thanks! 😄
