Through a convoluted chain of dependencies, obs_lsstSim has inherited an optional dependence on testdata_deblender. Because lsst_sims depends on obs_lsstSim for the simulated camera model, this means that eups distrib install lsst_sims -t sims tries to install testdata_deblender, which fails if you don't have git-lfs installed and properly configured. testdata_deblender should be masked so that Jenkins' run-publish ignores it the way it ignores afwdata.
