That's not a Squeak problem except that your sources or changes file is
munged - probably because you're on a Mac and UnStuffIt/StuffIt Expander
did you the "favor" of converting line endings, thus disrupting the offsets
into the file Squeak uses to fetch the source of methods. This is the MFAQ
for new Squeak users, and a frequent topic on this list. Please don't
cosider it a weakness of the language - any language's source files can be
damaged.
Of course it isn't a weakness of the Smalltalk language,
but it *is* a weakness of the Squeak implementation that things
can go this wrong with a key file without the system noticing.
In previous messages I reported some timing tests I did which showed that
checksumming key files need not be a performance problem; least of all is
this so during installation!
If the standard installation process on a Mac (download the file, click
on what you get and let it unpack itself) doesn't work, what _should_ I
do to get a working current Squeak?
