The very first version of Okra has been released!
If you do not have much experience using Common Lisp & gcc and the compiled libraries that come with this release do not work for you, you will probably have a hard time getting this to work.
The release can be downloaded from the Okra project page:
http://www.common-lisp.net/project/okra/
This release is released as a gzipped tarball since the source is in too much flux right now for other people to contribute. Future versions of the source code will be hosted at GitHub once things have settled down. The project page will stay at common-lisp.net.
