Xen devel - Jun 2006 - Missing Information about compile requirements in source package

Hi,
It seems that to compile xen, one also needs the packages
ncurses-dev and transfig (on Debian, no idea what''s their name in
other distributions).
Without transfig no docs, also no man pages seem to be build which is
quite bad, without ncurses dev the buidl fails completely.

This should probably added to the list of software required to build Xen in the
README file.

It would also be cool if the build process would check theses
dependecies _before_ string the build.
At least for the ncurses-dev dependency, which makes the build
completely fail if not fulfilled, but only after some minutes of
compiling - it''s not funny for users to see a build fail after some
time of waiting with an error that could have been checked before.

BTW: tried to get a bugzilla account for this, but I am unpatient and
got no bugzilla login after some minutes of waiting...

I expect only xentop depends on ncurses-devel. We could detect that 
dependency in the build system and not build xentop.

There''s also a dependency on python2.3-dev :

	...
	make[2]: Entering directory
`/home/miller/xen/hg-unstable/tools/python''
	CFLAGS="-O2 -fomit-frame-pointer -DNDEBUG -m32 -march=i686 -Wall
-Wstrict-prototypes   -D__XEN_TOOLS__" python setup.py build
	running build
	running build_py
	running build_ext
	error: invalid Python installation: unable to open
/usr/lib/python2.3/config/Makefile (No such file or directory)
	make[2]: *** [build] Error 1
	make[2]: Leaving directory `/home/miller/xen/hg-unstable/tools/python''
	...

Sorry, I''ve just realised that this is already documented in the
README.

I tihink, as for just building without manpages, this is quite inconventient
for most, especially starting users.
Such basic tools should not silently kept unbuilt, but the buid should stop.
There shoud then be some build option like "--no-xentop" and
"--no-docs"  to build xen explicitly even if the buid dependencies for
these aren''t met.
