[plt-scheme] Errors building 4.2.5 on Linux

What exactly does --enable-shared do? I think, very vaguely and
without much understanding, that it allows multiple users to share a
single copy of certain things in memory. That may be completely wrong.

If that's correct, how big an impact will not using --enable-shared
have on my school lab where I have a bunch of thin clients all running
DrScheme on the same server? Right now, everything runs reasonably
snappily. Is that likely to change?
