@sean if you install ldc2 like: $ cmake . -DD_VERSION:STRING=2 -DCONF_INST_DIR:PATH=/etc $ make -j4 VERBOSE=2 $ make -j4 install
and try install druntime from https://github.com/D-Programming-Language/druntime.git I can't because make file is only for dmd. What i try to said, yes we need 1 druntime so for this reason druntime installer need support at least dmd, ldc, gdc. But is not case currently. And for this reason d2 can't go to Fedora 16. Because ldc2 use cmake for build 3 projects (ldc, druntime, phobos) I need 3 installer separately. And ldc2 use a druntime fork! thanks for any answer :-)
