Problem with Drush/Exec[drush.autocomplete.install]?

[SummittDweller]

I'm trying to provision a precise64 box with Drush using this module but I must have a dependency issue somewhere in the mix? On my initial provisioning attempt I consistently get this:

Notice: /Stage[main]/Drush/Exec[drush.autocomplete.install]/returns: executed successfully
Notice: /Stage[main]/Drush/Exec[drush.autocomplete.source]/returns: bash: /etc/bash_completion.d/drush.complete.sh: No such file or directory
Error: bash -c "source /etc/bash_completion.d/drush.complete.sh" returned 1 instead of one of [0]
Error: /Stage[main]/Drush/Exec[drush.autocomplete.source]/returns: change from notrun to 0 failed: bash -c "source /etc/bash_completion.d/drush.complete.sh" returned 1 instead of one of [0]

But on subsequent provisioning attempts these execs run without error.

I'm trying to understand the intent of the command within drush.autocomplete.install but it's not entirely clear to me. In my case the php -i | grep... portion of that command returns:

/usr/share/php
/usr/share/pear

But the later of these, /usr/share/pear does not exist. Should it?

I've tried running the subject command manually after provisioning and have had limited success. Specifically, I'm able to build a suitable "ln -s -f..." statement and create the target link using that as long as I do so under sudo, but this is clearly not happening during my Puppet run.

Does any of this make sense? Any clue what might be wrong here? Thanks in advance.

Drush is actually dropping PEAR support soon. I really need to rewrite this module to use Composer instead.
