is there a way to specify additional packages to install for a pants plugin? I'm loading it through backend_packages but need to get it to install some things with pip before it can run the plugin

This is unintuitive, but you add them in the 
plugins
option in 
pants.ini
, under 
[GLOBAL]
E.g.,
Copy code
plugins: [
    'pantsbuild.pants.contrib.codeanalysis==%(pants_version)s',
    'pantsbuild.pants.contrib.go==%(pants_version)s',
    'pantsbuild.pants.contrib.python.checks==%(pants_version)s',
    'protobuf==3.2.0',
    'setuptools==30.0.0',
    'leveldb==0.20',
    'boto3==1.7.7'
  ]
The first three are published plugins we’re consuming, the last 4 are requirements for our internal plugin, which itself is not listed here because we’re consuming that from inside the repo… So it’s a bit of a hack, but it works fine.
We reference the internal plugin thusly:
Copy code
pythonpath: [
    '%(buildroot)s/src/python',
  ]

backend_packages: +['toolchain.pants']
