I followed this instructions from the README listed below:

{{{
Building from git clone:

./reconfigure
rpmdev-setuptree
make srpm

Building the rpm:

make rpm

}}}

I ran srpm and it couldn't file comps-fe6.xml:

{{{
[root@spiro3 revisor]# rpmdev-setuptree
[root@spiro3 revisor]# make srpm
{ test ! -d revisor-2.0.4.0.3 || { find revisor-2.0.4.0.3 -type d ! -perm -200 -exec chmod u+w {} ';' && rm -fr revisor-2.0.4.0.3; }; }
test -d revisor-2.0.4.0.3 || mkdir revisor-2.0.4.0.3
list='glade conf revisor patches po'; for subdir in $list; do \
if test "$subdir" = .; then :; else \
test -d "revisor-2.0.4.0.3/$subdir" \
|| /bin/mkdir -p "revisor-2.0.4.0.3/$subdir" \
|| exit 1; \

(cd $subdir && \
make \
top_distdir="$top_distdir" \
distdir="$distdir/$subdir" \
am__remove_distdir=: \
am__skip_length_check=: \
distdir) \
|| exit 1; \
fi; \
done

P.S. To get it to just build I copied the comps-fc6.xml to the comps-fe6.xml because I wanted to build the srpm and rpm.
