The original mechanism to unbundle libraries in vmware-workstation has been commented out for a while (why? by whom?). Running vmware-workstation uses a mix of system and bundled libraries (why?). Dependencies specify all libraries, including those bundled. Need to introduce a +bundled-libs useflag (off=unsupported for now, ewarn), and start testing. I'll work on this over time, this bug is more "note to myself"...
in bug 559798, I added all gentoo-packaged libraries to the depends list. it appears that the majority of the binaries do linking manually (i.e. inside main, possibly via dlopen) and will prioritize system libraries. however, some reference older/newer versions of libraries or use those that are not present in gentoo.git. (obviously ignoring clear internal libraries)
There's an internal, customized library loader. It can be controlled via environment, e.g. VMWARE_USE_SHIPPED_LIBS=1 to use only bundled libraries. We're using that now.
