This should probably be fixed by @drewcrawford can you try using the new flag and confirm

This should be fixed for swiftpm by

hah fun, this might be an issue in llbuild, need to investigate

if there is a directory named = swift creates a dependency file: ``` java /private/tmp/Hello/=/.build/debug/_.build/main.swift.o : /private/tmp/Hello/=/Sources/main.swift /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/x86_64/Swift.swiftmodule /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/x86_64/SwiftOnoneSupport.swiftmodule /private/tmp/Hello/=/.build/debug/_.build/main~partial.swiftmodule : /private/tmp/Hello/=/Sources/main.swift /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/x86_64/Swift.swiftmodule /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/x86_64/SwiftOnoneSupport.swiftmodule /private/tmp/Hello/=/.build/debug/_.build/main~partial.swiftdoc : /private/tmp/Hello/=/Sources/main.swift /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/x86_64/Swift.swiftmodule /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/x86_64/SwiftOnoneSupport.swiftmodule ```...

agreed, clear all data makes sense. I'll took a shot at implementing this @ https://github.com/nickoneill/Pantry/pull/34
