There is a lot of relevant information in UPDATING, but this file
doesn't focus on ports, and some changes that affect ports aren't
mentioned. You can find some workarounds or IGNORE settings in
individual port Makefiles based upon OSVERSION, some open PRs which
describe known problems (and, occasionally, solutions), and a partial
list of problems at:

http://wiki.freebsd.org/PortsBrokenOnCurrent

(but this last listing is somewhat incomplete and out-of-date). You
can also find build logs at:

http://pointyhat.freebsd.org/errorlogs/

Efforts to find and fix these problems will accelerate after the
slush/freeze that will precede the release of FreeBSD 9.
