Could you provide any clue about how to reproduce this error?

A copy of the build failure and a copy of that directory's
Makefile.am would be a good start.  (The 47-byte attachment in 
bugzilla is dummy.)

As far as I can tell, if two .Po and .Plo files share the same
.Tpo files, it means that you are trying to compile the same
source both with and without Libtool.  Automake is expected to
diagnose an error ("object `util.o' created both with libtool
and without") in this case, since that is subject to other kind
of failures.  The manual has a section explaining this error and
how to work around it.

Is this version of Automake actually run?  (building a package
does not necessary imply running Automake.)  Use `head Makefile.in' 
to know what version is actually used.
