Problems building packages with libtool

[<rjs%fdy2.demon.co.uk@localhost>]

I'm getting build errors with several packages that depend on libtool
on NetBSD 5.99.55 (i386 and amd64).

An example:

===> Building for desktop-file-utils-0.15nb1
/usr/bin/make  all-recursive
Making all in src
/bin/sh ../libtool --mode=link gcc  -O2 -I/usr/pkg/include -I/usr/include -Wall 
-Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs 
-Wpointer-arith -Wcast-align -Wsign-compare   -L/usr/pkg/lib -Wl,-R/usr/pkg/lib 
-L/usr/lib -Wl,-R/usr/lib -o desktop-file-validate  keyfileutils.o  validate.o 
validator.o -Wl,-R/usr/pkg/lib -L/usr/pkg/lib -lglib-2.0 -lintl 
libtool: link: unable to infer tagged configuration
libtool: link: specify a tag with `--tag'

Any ideas ?
