This makes sense.

But this doesn't. If you want to use constructs like
$(shell ...), you can throw all configure away and write
a plain old nonportable Makefile directly embedding these.
Autoconf works by
1. Finding information about the system using portable shell
code.
2. Filling templates (of Makefiles, config.h and often of
other files too) with these information.
This way the generated files can avoid the use of special
smart (and nonportable) features because the smartness is in
configure.

There is neither @GLADE3_PIXMAP_DIR@, nor
@GLADE3_MODULES_DIR@ nor @[EMAIL PROTECTED] So your
AC_SUBST has nothing to do. Please read autoconf
documentation, but you should at least know AC_SUBST creates
@foo@ substitutons and AC_DEFINE creates config.h #defines.
You need at least something like
configure.ac:
PKG_CHECK_MODULES(GLADE3, glade-3)
GLADE3_PIXMAP_DIR=`pkg-config --variable=pixmapdir glade-3`
GLADE3_MODULE_DIR=`pkg-config --variable=moduledir glade-3`
GLADE3_CATALOG_DIR=`pkg-config --variable=catalogsdir glade-3`
AC_SUBST(GLADE3_PIXMAP_DIR)
AC_SUBST(GLADE3_MODULE_DIR)
AC_SUBST(GLADE3_CATALOG_DIR)
Makefile.am:
gladegnomedbdir = @GLADE3_MODULE_DIR@
catalogdir = @GLADE3_CATALOG_DIR@
...

Whatever.
