Upstream stopped supporting LTS 1.6.* releases. Let's move to the 2.x branch which only supports LMDB (patched to use MDB_WRITEMAP) and uses __thread (thus, needs clang or lang/gcc). The config format changed a bit, /usr/local/libexec/knot1to2 might help. Most work done by Alexis Vachette, ok fcambus@
