OSX 10.6 clang / llvm circular dependency

[Chris Jones]

Hi,

Clearly clang-7.0 and llvm-.7.0 cannot depend on clang-7.0 as a build 
dependency, that will never work.

I do not see this though myself, in my OSX10.6 VM. There they both 
depend on clang-3.7 to build. See below. This is fine.

You must have done something locally in your checkout to cause this 
circular dependency... ??

cheers Chris

clang-7.0 @7.0.1 (lang)
Variants:             [+]analyzer, assertions, debug, [+]emulated_tls, 
[+]libstdcxx, universal

Description:          Clang is an LLVM native C/C++/Objective-C 
compiler, which aims to deliver amazingly fast compiles (e.g. about 3x 
faster than GCC when compiling
                       Objective-C code in a debug configuration), 
extremely useful error and warning messages and to provide a platform 
for building great source level
                       tools. The included Clang Static Analyzer is a 
tool that automatically finds bugs in your code, and is a great example 
of the sort of tool that can
                       be built using the Clang frontend as a library to 
parse C/C++ code.

Description:          The LLVM Core libraries provide a modern source- 
and target-independent optimizer, along with code generation support for 
many popular CPUs (as well
                       as some less common ones!) These libraries are 
built around a well specified code representation known as the LLVM 
intermediate representation ("LLVM
                       IR").

Not sure how to work around this, but it is quite a PITA to do the equivalent of "sudo port upgrade outdated" manually port by port ... Hoping someone can either fix this issue or tell me how to work around it so that I can make faster progress ... thx! - MLD
