And by the way, if you remove extio.o1 you'll have other warnings concerning rfc1423.o1 and http.o1
Remove those too and you can run snowman.
So this is a compilation bug.
Okay so the problem was clearly in extio. I tried requiring that in a test package and
invoked it with snow -- test.scm and had the same error.
And I reinstalled snow with only gambit to see if there were any warnings or errors and

... etc
As you can see, extio compiles correctly because there are no define or define-macro in the package* header.
I'll see Marc with this problem.
