$ spack help --all| grep diy
  diy                   do-it-yourself: build from an existing source directory

I haven't explored this mode though. [but useful for packages that are
not already represented in repo]

This more was in instructions for one of the packages - but then I
couldn't figure out equivalent of 'spack spec' vs 'spack install'
[query and check dependencies before installing] with diy

Its not ideal - but having local changes in our spack clones (change
git url, add appropriate version lines to branches that one is working
on) is possible [for a group working in this mode]. But might not be
ideal for folk who might want to easily do a one off PR - in this
mode.
