Too many binary packages are missing

Maybe some other ports have licenses that prevent the distribution of
packages, but not lang/gcc45 and devel/qt4-corelib.  Where did you
instruct portupgrade and the base system package tools to look for
them?   Is your ports tree up-to-date?  I see, on the ftp servers:

http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6-stable/lang/gcc-4.5.2.20100923.tbz

http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-7-stable/lang/gcc-4.5.2.20100923.tbz

http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.0-release/lang/gcc-4.5.0.20090924.tbz

http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/lang/gcc-4.5.1.20100701.tbz

ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8-stable/lang/gcc-4.5.2.20100923.tbz

http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-9-current/lang/gcc-4.5.2.20100923.tbz

Also:

http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6-stable/devel/qt4-corelib-4.6.3.tbz

...

etc.  Why did you think that they were missing?  Incidentally, the
latest version of lang/gcc45 is a snapshot of gcc 4.5.2, so ports or
packages that want gcc 4.5.0 are outdated.

There are localized versions of the stable OpenOffice port available
for FreeBSD 8-* (and some older ones for FreeBSD 7-* ) available at:

http://ooopackages.good-day.net/pub/OpenOffice.org/FreeBSD/

although the latest snapshots appear only to be built for U.S. English
and Japanese at that server.
