Fix the build with what seems to have been the intended change from 1.28
It seems that the intention was to make a new BUILD_DEPENDS with the same
content as the existing RUN_DEPENDS, but one line was missed, causing
neither to work. So instead, make BUILD_DEPENDS equal to the old
RUN_DEPENDS, and use the := method to set RUN_DEPENDS, in part because it
helps avoid this kind of error.
- Update to 0.1615
This commit differs from the patch submitted with the PR
in that it updates the port to an even newer version and
also updates the minimal version of a dependency.
