It was added long long time ago: # FIXME: The depedencies of EFL 1.9 can not be updated unless MAKEFLAGS is set to '-j1'. os.environ['MAKEFLAGS'] = '-j1' The problem was that we used setting MAKEFLAGS=-j30 for icecc setup previously and make install of EFL can't handle parallel installing. But building with icecc properly is to use NUMBER_OF_PROCESSORS environment variable, which is passed to make by jhbuild, but not for make install commands, because make install shouldn't be parallelized. So the solution is that folks don't use MAKEFLAGS to set -jXXX and we won't need this hack anymore.
