That looks like a bad editing of the ODBM_File/hints/svr4.pl:

########################## hints/svr4.pl #########################
# Some SVR4 systems may need to link against routines in -lucb for
# odbm.  Some may also need to link against -lc to pick up things like
# ecvt.
$att{LIBS} = ['-ldbm -lucb -lc'];
###################################################################

"Some" includes Unisys 6000 (or something like that).  I don't know
if it includes anything else.  It doesn't include Unixware 2.1, but it
might include Esix.  It's *really* hard to get accurate info.

"May" because some do and some don't, and any listing gets out of date
quickly as vendors issue different versions, and probably more than
half the info you *do* get about specific versions is wrong.  Hence all
the vague weasel-words.
