That statement in the docs is correct.

perl-Qt (puic specifically) is needed for building OSCAR. This is only
necessary if you are using Subversion checkout (you need to pre-install
that prior to running ./autogen.sh && ./configure). If you are using a
distribution release and/or nightly tarball, this is not necessary and
perl-Qt will simply be installed as a prereq.
With 4.2, there might have been a warning stating that you cannot build
perl-Qt widgets - that particular issue is fixed in trunk.

That's not necessary at all, they are provided in share/prereqs and will
be automatically installed (provided you have the RPMs in the
corresponding distro/fc5-x86_64 directories).

It is usually recommended that you simply rebuild the SRPMs on fc5
x86_64, this is because some of the applications are built against
specific versions of Perl, Python, etc. - so as you have experienced
some times the versions do not match up between RHEL4 and FC5 and you'll
run into issues.

It may not be a bad idea to add these to the start_over script...

This is not necessary, since Fedora Core 5 comes with mysql-server in
its distribution already.

The start_over script is mostly used by developers and is not supported
in any way (this may change in the future). We usually recommend users
just re-install the headnode (kickstart is handy for quick
re-provisioning, or VMWare!).
Mike, what do you think?
> Thanks for helping me get this far!
BTW, if you have built RPMs on Fedora Core 5 x86_64 that are not
currently in the repository, I'd appreciate it if you can send them to
me, so that I can upload them into SVN.
Thanks,
Bernard
