Hi Frank,
It looks like you grepped through the source and grouped the results, rather than errors that block you. I've checked most of the files above. Some places are uncalled functions, the *postgresql-postgresq.xql* is already removed since a few weeks, a few issues are in non-maintained packages not in the oacs-5-9 (events), xotcl-core-po is unknown for me, xotcl-core is a false positive, .. and yes, the docs should be update (Are there vounteers?)
Below is a discussion from a few years ago:

In case, there are real issue, a bug-tracker entry would be appreciated.
