That's probably the same problem I posted a few weeks ago which seems to be
related to autoconf 2.60. autoconf complains about an undefined variable
datarootdir. This undefined variable gets in the packages .po file and
pkg_config fails on this file, as it cannot expand the variable.

I worked around by changing libXt's configure.ac:

--- a/configure.ac
+++ b/configure.ac
@@ -74,7 +74,7 @@ AC_ARG_WITH(appdefaultdir,
         AC_HELP_STRING([--with-appdefaultdir=<path>],
                        [Set app-default directory (default: ${datadir}/X11/app-defaults)]),
         [appdefaultdir="$withval"],
-       [appdefaultdir=${datadir}/X11/app-defaults])
+       [appdefaultdir=${prefix}/share/X11/app-defaults])
  AC_SUBST([appdefaultdir])
  
  # Replacement for Imake ToolkitStringsABIOptions, controls string tables

But this isn't a correct fix. See also
