depends_on :clt

[samueljohn]

Just like depends_on :xcode, I'd like to have depends_on :clt.

Some formulae do not yet compile with only Xcode, though I am trying to fix them one by one.
Some are so hard to fix, that I gave up fixing or I don't want to mage huge patches. For example qt and pyqt are very hard.

However, there is one issue and I need a little bit help:

• When I install a bottle, I'd like to skip this dependency, but I don't know how.

[samueljohn]

ping @adamv and @jacknagel because you both worked on the depends and options features, right?

[jacknagel]

I have code to allow bottles to skip build-time deps, but it depends on some work @adamv is doing that isn't merged yet.

[adamv]

Which code?

[samueljohn]

I want your code :-)
I want it all.
I want it now.
(/me had too much coffee, it seems)

So, I should use it like depends_on :clt => :build (or make it a build time dep on default).

[jacknagel]

@adamv the reorg. in FormulaInstaller that is part of the optional/recommended work.

Part of it is here: https://github.com/jacknagel/homebrew/compare/deps
