After building with LMDB 0.9.18 and following steps in the README: Contents of README have changed, this should still give an idea of the problem, reproduction steps in later comment:

$ git -C sqlightning checkout benchmarking && tclsh sqlightning/tool/speedtest.tcl

make LMDB_0.9.17.html or make LMDB_0.9.18.html can also now be used to reproduce.
