Once I got VMWare Player installed, I ran into a few issues. My first issue was that it was unable to find a specific symbol... this was in relation to recompiling dev-cpp/gtkmm with the use flag "accessibility". Once that is rebuilt you also need to rebuild x11-libs/libsexy, dev-cpp/libsexymm and x11-libs/libview. Once those are rebuilt, the error about the missing symbol went away, then it was on to a whole new error message.

The next error message seems to come only when dbus is enabled

process 29624: Attempt to remove filter function 0x7f481078f444 user data 0x7a5490, but no such filter has been added
D-Bus not built with -rdynamic so unable to print a backtrace

Now I searched far and wide for this, and the only solution I found for a while was just to disable dbus completely. I didn't want to do this because I've got a few programs that are using dbus. After searching more, I found something else. Finally, a Gentoo Bug that tells me what's wrong! It appears by the bug report that if you have dbus running, you must also have hald running. Once I started up hald, vmplayer has worked perfectly.

Hopefully this will help someone and save them from pulling their hair out unlike I did.
