Hi there Just for the records.
I finally managed to build GCC with D support myself (without using the overlay). What I did: - Download and enpack a tar for GCC 4.8.2 - Clone the git repo from gdcproject.org - Check out the appropriate branch in the git repo - Run the setup-gcc.sh script - Configure GCC (including --enable-languages=d) - Make GCC -- Greetings Elias
