Comment (by ryandesign):

 Earlier in the log it says:

 {{{
 :info:build [  1%] Generating
 outline_atomic_helpers.dir/outline_atomic_ldclr2_4.S
 :info:build [  1%] Generating
 outline_atomic_helpers.dir/outline_atomic_ldclr2_4.S
 }}}

 The fact that it's trying to generate it twice implies that Makefile
 dependencies are not declared correctly in this project and that the
 problem might only affect parallel builds and that simply retrying might
 allow the build to succeed. If it does not, you can retry and add
 `build.jobs=1` to the end of the `port install` or `port upgrade` command
 line to disable parallel building.

 Wrong Makefile dependencies would be a problem that needs to be reported
 to the developers of clang so that they can fix it.
