Package dependencies are there to tell WPKG that another package is to be 
installed _before_ the a package which defines the dependencies.

I thought about using conditions in depends statement in a package but this 
would not help too much I guess since if there is no office installed at all it 
would not check the dependency but still install BCM.

I think the solution here is not to define a dependency on a package but simply 
define a condition in your profile.

For example (not verified, might contain bugs) in profiles.xml:

<profiles>
<profile id="default">
   <package package-id="office-2010-business" />
   <package package-id="bcm">
     <condition>
       <check type="uninstall" condition="exists" path="Microsoft Office.*"
     </condition>
   <package>
</profile>
<profiles>

This would install BCM only if office is already successfully installed (any 
edition). Sure you can also use complex checks including AND/OR checks to verify 
specific Office versions installed where BCM is compatible with.

So during first WPKG run the profile above would install Office 2010 only. No 
BCM will be installed since the condition is not met (yet). During subsequent 
runs WPKG would also deploy BCM since the condition is met and BCM is therefore 
added to the profile.
