Not offhand, but attached is my ~/.rpmmacros which might be helpful.
The __arch_install_post stuff requires the fedora-rpmdevtools package
from Extras installed.

Yes.  See "rpm --eval %{_lib}".  Also, "rpm --showrc" shows much more
than you ever wanted to know :)

Use C-c C-e while in rpm-spec-mode.  I usually just hit enter to the
resulting "Change log entry:" prompt, and fill in the entries manually.

No, sometimes you want to inspect the build root contents after the
build has completed.

By the way, for %post and %postun scriptlets that only
invoke /sbin/ldconfig and nothing else (haven't looked if it's the case
in this package), use "%post -p /sbin/ldconfig" and the same for postun;
that way rpmbuild groks the dependencies automatically, no need for
PreReq or any other form of explicit dependency for ldconfig.

Oh, and there's quite a bit of info in the Wiki; when you have specific
questions, it might be good to try the (text) search at
