For `require' (or `require-for-syntax') to work properly,
the `extension-registry' has to be set up. The easiest way is
to create a directory called `.chicken-registry' in your $HOME
directory and run `csi -setup', like this:

% cd $HOME
% mkdir .chicken-registry
% csi -setup

This installs the extension-registry, with entries for the core
extensions (library units).
Then everything should work. Note that `require' searches the current
directory and the $CHICKEN_INCLUDE_PATH as well (if the extension
can not be found). For that reason executing the require in the
src directory was successful. But that gave you only the source-version,
of course. With the registry properly set up, you can load the compiled
version.


Thanks for using Chicken!
