Comment 2 for bug 578806

The commit (http://git.omp.am/?p=conky.git;a=commit;h=01e3bb62a2136d2ff6a6d1ec01d472fb01bc31e8) was not in the 1.8.0 or 1.8.1 branches.
Until upstream releases it, you won' t get it distributed. If you really want to have it in advance than I can only suggest you compile from an updated git snapshot.
