Dependency specifications in pip

[astrozot]

Hi,

is it possible to use pip within stash to install packages that include dependency specifications in setup.py such as

  install_requires=[
      'ProxyTypes;python_version<"3.0"',
      'objproxies;python_version>"3.0"'
    ],

I have tried at it seems to fail (it takes the entire line as a package, without splitting the dependency specification).
