The OSX installer is different than the Linux thing -- the former is
just a drag-and-drop directory, no administrative cleanup.  On Linux
it's more popular to have the files spread according to the FHS.  This
kind of setup (the Linux thing) makes it difficult/impossible to have
multiple versions installed system-wide -- for that, it is easier to
have the single-directory installation kind which is essentially the
same as the default OSX thing.

You could create the link manually every time you install a new
version, or you could rename the PLT tree every time you drag+drop a
new one.
