You're right, it is a good idea to learn about compiling code if you're going to get on in the PD world!

What the error message is telling you is that the compiler can't find alsa/seq_event.h in its include path (all the -I <directory> paths). To fix this, you should create a directory called alsa inside dssi/include and move seq_event.h into it. I have now updated the CVS to reflect this.

In general you should keep header files in some standard location, so other build systems can find them. /usr/local/include is the usual place on *n*x systems.

Sorry about that; I haven't got around to making a new help patch to reflect the changes since version 0.8. These include a new mechanism for loading plugins and a new inlet/outlet structure.

To load a plugin, just type its name (easier), e.g. sine_faaa, or type the path to the library (faster) followed by the plugin name .e.g /usr/local/lib/ladspa/sine.so:sine_faaa. To list all plugins and locations send a |listplugins( message

At any rate, an incorrect argument shouldn't crash PD, so I need to fix that. Could you send me the file pd.crash.log
