+As we start updating packages for Red Hat 6.2, I'd like to see packages
+start to make use of build dependencies. Basically build dependencies are
+just like install dependencies, but they are resolved against the build system
+just after parsing the spec file. Syntactically, build dependencies look just
+like install dependencies in a spec file with "Build" prefixed:
+
+	BuildPrereqs:
+	BuildRequires:
+	BuildConflicts:
+
+All the above dependencies include versions, files, existence/range tests, etc.
+The build dependency checking can also be turned off with --nodeps if necessary
+just like install dependency checking can. Eventually, build dependencies will
+be automated in rpm, but the major impediment to that effort is the engineering
+required to maintain the pretense that src rpm's are "noarch".
+
+Meanwhile, I've added a package called "InDependence-1.0" to powertools-6.2
+that may be of use in detecting build dependencies that can be added to
+spec files as part of rebuilding packages for Red Hat 6.2.
+
+Here's a short example of how to generate the package/file names that were used
+while building gnorpm using InDependence:
+
+	rpm -U /mnt/redhat/comps/powertools/6.2/i386/InDependence-1.0-3.i386.rpm
+	rpm -i /mnt/redhat/comps/dist/6.2/SRPMS/gnorpm-0.9-11.src.rpm
+	cd /usr/src/redhat/SPECS
+	dep -detail rpm -ba gnorpm.spec >& xxx
+	...
+	(the build will take longer since both dep and strace are pigs)
+	...
+	grep -- '::' xxx > yyy
+
+=========================================================================
+Aside:	The dep perl wrapper is a "pig" only because it's exec'ing
+		rpm -qf <filename>
+        in order to turn filenames into package names. There are easier/faster
+	ways to get this information...
+
+	There's no way to speed up the
+		/sbin/strace -q -etrace=open,execve -o ...
+	command itself. The eventual implementation in rpm will snatch the
+	same open/execve syscalls using LD_PRELOAD.
+
+	Patches cheerfully accepted :-)

+The information can be used to generate build prerequisites. What is still
+needed is a sensible approach on
+
+	1) eliminating obvious common dependencies (e.g. libtool, egcs).
+	2) identifying (and removing for now) per-platform build dependencies.
+	3) deciding on whether to add the build dependency on a file or on the
+	package that contains the file.
+	4) if adding a dependency on a package, choosing version ranges as
+	appropriate.
+
+but that's up to individual packagers.
