Hi,

I just decided to do a git pull.  It looks as though there is are additional dependencies for OpenVDB that may not have been taken into account at least for OS X:

OpenEXR

TBB

Boost

Here is the error for ILM which is in OpenEXR.

## Building OpenVDB...

fatal: destination path 'openvdb' already exists and is not an empty directory.

HEAD is now at c5e9e294... Merge pull request #580 from Idclip/7.0.0_releasecandidate
