If I uninstall clang using conda I now get:

(base) Davids-MacBook:fred david$ dub
Performing "debug" build using /Library/D/dmd/bin/dmd for x86_64.
fred ~master: building configuration "application"...
Linking...
x86_64-apple-darwin13.4.0-clang: No such file or directory
core.thread.ThreadError at src/core/thread.d(3093): Unable to load 
thread state
----------------
Error: linker exited with status 255
/Library/D/dmd/bin/dmd failed with exit code 1.


It seems like dub has somehow gotten entwined with the anaconda 
compiler - any ideas how to fix?
