Javier,
Thanks for sharing your experience. It's always good to hear what other people are doing.
Re: the changes in the .sql files, this is documented in the Installation Guide.
Re: www/custom-sections/file/get-binary-file.tcl, you most likely hit a bug that was left-over. Please take a look at our bug tracker and, if nobody has submitted that bug report, submit it (openacs.org/sdm/)
Re: patches. Yes CVS can apply patches IIRC. What patches are you talking about?
