Missing dependency of cl-prevalence when running weblocks-demo

[hija...@gmail.com]

Page http://weblocks.viridian-project.de/installation gives enough information to install Weblocks and get a grasp of it by demo. However, on step 4, when one should load the demo by issuing (asdf:oos 'asdf:load-op 'weblocks-demo) command, SBCL gives me error about missing CL-PREVALENCE library. I am not so proficient with dependency checking in CL, but this library should definitely be noted as dependency either in quicklisp package or in weblocks-demo ASDF system. Maybe weblocks-demo itself should be packaged into quicklisp. Sorry, I cannot do this myself yet, but I think this should be known to the community.

And yes, this issue can be fixed by calling (ql:quickload 'cl-prevalence) before step 4 of installation tutorial.
