puppet, virtualenv, and .bashrc

Morning,

I am trying to do some environment setup on our developer's virtual
boxes that we use vagrant+puppet to build.  We install a python app,
create virtualenv's for the different pip requirements, etc.

Problem is that there are some custom bash macros that are available
in our virtualenv as they are sourced in the .bashrc

ie.,
~panama/.bashrc
{code}
...
source /usr/local/python/bin/virtualenvwrapper.sh
...
{code}

but when my puppet scripts tries to execute those macros, it's unable
to as it can't load the virtual env.

sample.pp
{code}
...
    exec { 'panama-eggs':
        path    => ["/bin","/usr/bin","/usr/local/python/bin"],
        environment => ['WORKON_HOME=/home/panama/.virtualenvs',
'PIP_LOG_FILE=/tmp/pip-freeze-prod.log', 'PIP_VIRTUALENV_BASE=/home/
panama/.virtualenvs', 'VIRTUALENVWRAPPER_PYTHON=/usr/local/python/bin/
python'],
        command => "workon dev && mmf_eggs",
        logoutput => "true",
        user  => "panama",
        group  => "panama",
        require => [Exec["mmf-panama-install"], Exec['symlink-panama-
post-activate']]
    }
...
{code}

results in:
...
err: /Stage[main]/Panama/Exec[panama-eggs]/returns: change from notrun
to 0 failed: sh: workon: command not found
...

fyi
# .bash_profile
if [ -f ~/.bashrc ]; then
   source ~/.bashrc

Any ideas on how to get puppet to recognize the macros in the "source /
usr/local/python/bin/virtualenvwrapper.sh" for user panama?

Cheers,
