No problem, I have been busy as well. :)

I got them. These are installed (in /usr/local/) by the coinmp package:

lib/libCbc.so
lib/libCbc.so.3
lib/libCbc.so.3.9.6
lib/libCbcSolver.so
lib/libCbcSolver.so.3
lib/libCbcSolver.so.3.9.6
lib/libCgl.so
lib/libCgl.so.1
lib/libCgl.so.1.9.7
lib/libClp.so
lib/libClp.so.1
lib/libClp.so.1.13.8
lib/libClpSolver.so
lib/libClpSolver.so.1
lib/libClpSolver.so.1.13.8
lib/libCoinMP.so
lib/libCoinMP.so.1
lib/libCoinMP.so.1.8.3
lib/libCoinUtils.so
lib/libCoinUtils.so.3
lib/libCoinUtils.so.3.10.10
lib/libOsi.so
lib/libOsi.so.1
lib/libOsi.so.1.12.6
lib/libOsiCbc.so
lib/libOsiCbc.so.3
lib/libOsiCbc.so.3.9.6
lib/libOsiClp.so
lib/libOsiClp.so.1
lib/libOsiClp.so.1.13.8
lib/libOsiCommonTests.so
lib/libOsiCommonTests.so.1
lib/libOsiCommonTests.so.1.12.6

That looks very similar to what I had. I am currently traveling but I will give it a try when I return home.
