1) libwebsocket-dev on Debian is at 1.2.2. grr. I cloned from github and build as per README.build.md
2) mysqlclient is failing

Probably similar issue? Don't care. Not interested in mysql right now. SO, I tried to use ./configure to remove by reading ./configure --help and came up with this:

    ./configure --ext=socket,sqlite,websocket


BUT mysqlclient still shows up in all the mod flags?

```

Ready to run "make". For options run "./configure --help"
```

Which still fails. I wound up manually removing mysql from the make.conf file that was generated (setting the flags to -DJSI__MYSQL=0 and so forth. That then build successfully. 

Then, when I try to run make install, everything fails because it can't find MySql.so!

Anyway, I was able to run it ONCE from the build directory. Then I got cocky and first I rebuilt everything to write the email (doh!), then I modified the MakeFile for make install and removed the MySql line. It installed, but nothing works now:

    ./jsish: error while loading shared libraries: libwebsockets.so.10: cannot open shared object file: No such file or directory

I tried re-installing libwebsockets but it didn't help.

Oh, and also the command line usage prompt seems to be incorrect:
