[racket-dev] possible bug with 5.* versions and zo files

When I went to rebuild the latest source this morning, I got the
following error from 'make install':

racket/racket3m -X "/home/samth/sw/plt/collects" -N "raco setup" -l- setup
raco setup: bootstrapping from source...
/home/samth/sw/plt/collects/unstable/private/compiled/expand_ss.zo::0:
read (compiled): code compiled for version 5.0.0.1, not 5.0.0.2

I was under the impression that "bootstrapping from source" was meant
to avoid this possibility, and that this error shouldn't happen.
After removing that file, I tried running 'raco setup', and got:

[samth at punge:~/sw/plt (master) plt] raco setup
raco setup: WARNING: collects/teachpack/compiled/info_ss.zo::0: read
(compiled): code compiled for version 5.0.0.1, not 5.0.0.2
collects/teachpack/compiled/info_ss.zo::0: read (compiled): code
compiled for version 5.0.0.1, not 5.0.0.2

Since this is the first time that we've had an increment in the
version number when starting with 5, I'm suspicious that that might be
related.
