Comment (by mouse07410):

 > We do want to continue having a method for people using MacPorts to test
 out the new assembler in a new version of {{{clang}}}, though

 Understood and agreed.

 However, we're discussing what should be the default, not what should be
 possible. And in my opinion, it should be **possible** to configure
 {{{cctools}}} to use whatever installed version of {{{clang}}} you want to
 point it at - but it should **not** install another version of {{{clang}}}
 unless I **explicitly** ask for it.
