Log Message:
Update scons to 1.1.0, scons-devel to 1.1.0.20081104.  Split
common makery into Makefile.common, add CONFLICTS for each package
referring to the others, as for now the manpages will conflict.

TODO:  Use ALTERNATIVES system?  How to handle manpages?

Many bug fixes and some feature/documentation enhancements.  The
web site goes into this in much detail; also, see CHANGES.txt
and RELEASE.txt in the source distribution.

Also, see the change to patch-aa which ensures we use ${PKGVERSION_NOREV}
to generate the version for the installation where appropriate.
