Re: is part of the wiki's hello world example broken?

[ipcore]

Your import.so should be named "hello.import.so". Doing `(import NAME)` 
will pull in NAME.import.so automatically. (You don't need to `,l 
hello.so`, btw)

In your example, when you run `(import test)`, the interpreter does not 
find a local test.so, and so goes looking for it in 
$CHICKEN_REPOSITORY_PATH. There, it finds and loads the "test" egg, as 
you can see from this line:


> ; loading /usr/local/chicken-5.2.0/lib/chicken/11/test.import.so ...


The documentation could probably be a bit more explicit on this.
