[drakma-devel] Error while trying to POST some JSON data

[Hans Hübner]

You can check out the latest cl+ssl - which contains a fix for the problem:

cd ~/quicklisp/local-projects/
git clone git://gitorious.org/cl-plus-ssl/cl-plus-ssl.git

Quicklisp will automatically find cl+ssl from that location.  Remember to
remove that checkout after you've upgraded to a newer quicklisp release
that has the fix in the future.
