The more portable the better as far as I'm concerned.

Heh, that's the nature of portability problems. They can be rather
difficult to predict. Thanks for your report.

I've just committed a fix to allow the default names of all of the autofoo
programs to be overridden via environment variables. So you should be
able to do something like:

	LIBTOOLIZE=glibtoolize ./autogen.sh

Hmmm... Do you have pkg-config installed? The autogen script is
supposed to check for it and print something like the following
message if it can't be found:

	autogen.sh: Error: Could not find pkg-config macros.
        	(Looked in /usr/share/aclocal/pkg.m4)
        	If pkg.m4 is available in /another/directory, please set
        	ACLOCAL_FLAGS=\"-I /another/directory\"
        	Otherwise, please install pkg-config.
	
        pkg-config is available from:
        http://www.freedesktop.org/software/pkgconfig/

So maybe the logic to do that check is broken? Or maybe there is some
other problem?
