If I include an open source library in my project that is licensed under the MIT license, but contains BSD-licensed code that requires attribution (correctly attributed inside the project), is it my responsibility to attribute it again if I decide to use that library?  Normally this is not a problem (I would just credit everyone regardless of the license) but on a mobile platform there is not a lot of real estate or efficient ways to show / bundle these licenses.
What are the requirements for an open-source license inside an open-source license?

BSD does not always require one to credit the author in the gui of their appplication.As a matter of fact, only the 4-clause license (original BSD License) requires attribution outside the source code and binary code of the application.It states as follows:Redistribution and use in source and binary forms, with or withoutmodification, are permitted provided that the following conditions are met:1. Redistributions of source code must retain the above copyright   notice, this list of conditions and the following disclaimer.2. Redistributions in binary form must reproduce the above copyright   notice, this list of conditions and the following disclaimer in the   documentation and/or other materials provided with the distribution.3. All advertising materials mentioning features or use of this software   must display the following acknowledgement:   This product includes software developed by the <organization>.4. Neither the name of the <organization> nor the   names of its contributors may be used to endorse or promote products   derived from this software without specific prior written permission.THIS SOFTWARE IS PROVIDED BY <COPYRIGHT HOLDER> ''AS IS'' AND ANYEXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIEDWARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AREDISCLAIMED.
