ltversion

        * Makefile.am (pkgmacro_DATA): We have to distribute
        m4/ltversion.m4 because it can be needed before the Makefile
        that generates it exists.

but:

libtoolize: warning: no serial number on 
`/usr/local/share/libtool/m4/ltversion.m4', not copying.

:-(

Cheers,

Patrick
