no, I don't think so.

I tried to follow this guide: http://wiki.freebsd.org/SubversionPrimer

and this book: http://svnbook.red-bean.com/

Are these adequate?

ok, will try

and is there a way to rebuild just a part of src? For example, 
if I've built all src already, then applied a patch to just one

it not that simple? 

I apologise if this is described in the manual somewhere.
