Grins and giggles: check the user's $PATH for directories under $HOME
and use the first one found?

Even if I tell it to? Also, you might want to avoid StarOffice (and
perhaps OpenOffice still does it these days).

You're missing a key point: *user installs should not require
root*. /usr/local is used for global installs, not for per-user

Those are valid only for OSX applications; Unixy stuff goes
elsewhere. By convention Fink uses /sw, MacPorts uses /opt/local,
and /usr/local is left for packages not owned by either; this makes it
a good place to install Cabalized programs (globally).

Again, not for Unixy stuff, only for full OSX applications and
frameworks. Try "ls -a" sometime.
