It fails to install manpages:
 ...
 + make install TOPDIR=/var/tmp/syslog-root  
MANDIR=/var/tmp/syslog-root/usr/share/man MAN_OWNER=mjt
 /usr/bin/install -o mjt -g mjt -m 644 sysklogd.8  
/var/tmp/syslog-root/usr/share/man/man8/sysklogd.8
 /usr/bin/install: invalid group `mjt'
 make: *** [install_man] Error 1

My userid is "mjt", but there is no such group on my system.
My primary group is "users".  The same stupid "workaround"
was implemented in uucp package -- it makes install
with OWNER=`id`, and also tries to chown mjt:mjt files...
I suggest to either add $MAN_GROUP (in additional to $MAN_OWNER)
to makefile (should be done at a first place), just remove
all that -o $MAN_OWNER -g $MAN_OWNER from makefile using perl
before doing first make (just easy), or install that manpages
from .spec file (only 4 pages) -- the last one should be
most easy.
