After a bit of research I found that BSD license is compatible with Apache 2.0 as of Jan 9, 2008. “On January 9th, 2008 the OSI Board approved BSD-2-Clause, which is used by FreeBSD and others. It omits the final “no-endorsement” clause and is thus roughly equivalent to the MIT License.” (Source: http://www.opensource.org/licenses/BSD-3-Clause)
One thing to consider is that for each individual open source software, you must follow the terms and conditions, as they apply. I would strongly suggest commenting blocks before and after each specific open source as it applies to each license, as well as commenting at the top of the file as defined as stated in each particular license. .
It seems to me that the license applies as far as each particular open source library relevant to that license is utilized. Once you step away from the use of a particular library, the license is no longer relevant.
Please don’t take my word for it, as I am not an attorney.
