Re: Libtool is linking the wrong library (location) in and I can't figure out what's causing it.

Sorry if this is terse, I'm on my phone. In the first case, you're using a library, liblog4cplus.so, that's installed in your home directory. Libtool sees this as outside the dynamic linker's path and adds a runpath so you're program will find the library at runtime without setting any environment variables. This is either helpful or a nuisance depending on your perspective.

One thing I'd suggest is rather than toying with prefix, which tells the tools where you're going to run the program from, use the DESTDIR make variable to stage the installation into your home directory.
