You cut off the trace just at the crucial line. It should say, e.g.:

ar ru librewrite.a config.o context.o info.o ldapmap.o map.o params.o rule.o 
session.o subst.o var.o xmap.o version.o
ar: creating librewrite.a

Anyway, I see no build errors here. Closing this ITS. Ask for help on the 
-technical mailing list.
