[fernsler]

If we intended for this to actually be the case, we might want to document it as such:

[fernsler@wwmach2 provision]$ sh ./autogen.sh && make dist && mzbuild && cp warewulf-*.rpm ~/warewulf-rpms
+ libtoolize -f -c
+ aclocal
+ autoheader
[ ... ]
checking whether we are using the GNU C compiler... (cached) yes
checking whether gcc accepts -g... (cached) yes
checking for gcc option to accept ANSI C... (cached) none needed
checking dependency style of gcc... (cached) none
checking for wwconfig... no
configure: error: wwconfig not found! (Warewulf common component)
[fernsler@wwmach2 provision]$

Intended and documented as such.
