Hello, I'm *very* new to Common Lisp and have only just started understanding how to use packages and asdf. I have a client/server application in mind, of which I've already written a fair amount (using the asdf module system), and I would like to use iolib to multiplex the i/o. I'm using sbcl 1.0.18.debian on an ubuntu 9.04 x86 box. I initially used asdf to set up iolib and it picked the iolib-0.6.0 package and downloaded/compiled a bunch of denpendencies. There were some problems compiling it concerning its dependencies, which I'm sorry to say I did not record or what I did to get around them--but it had to do with cffi-grovel not being a package asdf new about, and I believe I had to install cffi by hand before iolib would finish compiling becaue the grovel module was now part of the cffi. So, I started looking around for an example for how to use iolib, and found one online in the current sources for iolib called echo-server.lisp. It took a while for me to realize that net.sockets in the iolib-0.6.0 version was moved to iolib.sockets in the current sources, and after noticing that some other API changes happened and whatnot, I removed the iolib-0.6.0 site and system from my ~/.sbcl/{site,system} directory, removed the asd file symlinks, and git checked out the head of iolib. I put that checkout into the above mentioned place, hand set up the asd symlinks, and tried (require 'iolib) again. This is what I got: * (require 'iolib) ... compile lines ... debugger invoked on a SB-PCL::INITARG-ERROR in thread #<THREAD "initial thread" RUNNING {A834819}>: Invalid initialization argument: :SONAME in call for class #<STANDARD-CLASS CFFI-GROVEL:WRAPPER-FILE>.

I apologize for my gross misunderstanding of how to do all of this. I'm in the process of figuring it out. Thank you. -pete
