[plt-scheme] Question about building after svn update?

That will work (but you don't need "-install" just "install" and you
don't need to run setup-plt, "make install" does that for you), but
won't re-use any of the binaries. If instead, you did this:

  cd /source/pltosx
  make
  make install

you'd re-use the binaries.

Officially, this isn't supported because the dependency tracking in
the source tree is complex and not quite right. But, in practice, it
works 90% of the time. It won't work when any of the makefiles change
or when configure changes. If it doesn't work, you can just do the
below.

Your preferences file won't be affected. DrScheme uses the same one,
regardless of the build directories or the version of DrScheme (a few
preferences, like the language setting, are version-specific, tho).
