I'm glad you like it :D

No, the configure simply substitute the version number in
champlain.pc.in and champlain-gtk.pc.in generating champlain.pc and
champlain-gtk.pc.
The make step copies champlain.pc and champlain-gtk.pc respectively in
champlain-version.pc and champlain-gtk-version.pc.
So when it is generating the GIRs into the make step in champlain and
champlain-gtk subdirectories, the .pc files are still champlain.pc and
champlain-gtk.pc.

I'm thinking of export PKG_BUILD_PATH=$top_builddir somewhere inside
HAVE_INSTROSPECTION if, because champlain-gtk depends on champlain.

champlain-gtk/Makefile.am:
---
if HAVE_INTROSPECTION

-include $(INTROSPECTION_MAKEFILE)
INTROSPECTION_GIRS =
INTROSPECTION_SCANNER_ARGS = --warn-all --add-include-path=
$(top_builddir)/champlain
INTROSPECTION_COMPILER_ARGS = --includedir=$(top_builddir)/champlain

introspection_sources =
$(libchamplain_gtk_@CHAMPLAIN_API_VERSION@_la_SOURCES)

GtkChamplain-@CHAMPLAIN_API_VERSION@.gir:
libchamplain-gtk-@CHAMPLAIN_API_VERSION@.la
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_NAMESPACE = GtkChamplain
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_VERSION =
@CHAMPLAIN_API_VERSION@
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_LIBS =
libchamplain-gtk-@CHAMPLAIN_API_VERSION@.la
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_PACKAGES = gobject-2.0 gtk
+-3.0
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_FILES =
$(introspection_sources)
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_INCLUDES = Clutter-1.0
Gtk-3.0 Champlain-@CHAMPLAIN_API_VERSION@
GtkChamplain_@CHAMPLAIN_API_VERSION_NORM@_gir_CFLAGS = \
	$(SOUP_CFLAGS) $(GTK_CFLAGS) $(DEPS_CFLAGS) \
	-I$(top_srcdir) -I$(top_builddir)\
	-DCHAMPLAIN_COMPILATION -DCHAMPLAIN_GTK_COMPILATION

INTROSPECTION_GIRS += GtkChamplain-@CHAMPLAIN_API_VERSION@.gir

girdir = $(datadir)/gir-1.0
gir_DATA = $(INTROSPECTION_GIRS)

typelibdir = $(libdir)/girepository-1.0
typelib_DATA = $(INTROSPECTION_GIRS:.gir=.typelib)

CLEANFILES += $(gir_DATA) $(typelib_DATA)

endif
---

Any ideas?
