This is a good way to install packages that you've built by hand into (say) your home directory, but it will cause problems if you try to trick portage into doing it. The big problem is that no other packages are going to know where to find the thing you just installed. Everything else in the Gentoo repository is designed to use standard values of PATH, LD_LIBRARY_PATH, the compiler's include dir, PKG_CONFIG_PATH, etc. If you take one program and put it somewhere non-standard, then every package depending on it is going to break. If you install an *additional* copy (built by hand) in your home directory, that's fine -- the system copy will still be in the right place -- you just don't want to hide the system copy where nobody can find it.
