aclocal 1.8 APIVERSION perl 5.005

[Kevin Ryde]

Using automake 1.8 on an i386 freebsd 4.9 with perl 5.005_03 and
autoconf 2.59, I got an error from aclocal,

        aclocal: couldn't open directory 
`/home/kevin/mp/usr-new/share/aclocal-': No such file or directory

It seems to have lost the APIVERSION from that directory.  Putting a
print of $APIVERSION into aclocal showed it being undefined.  I got
some joy from adding to Config.pm,

        require Exporter;

But perl modules are a bit of a mystery to me, so maybe something more
is needed.

For what it's worth, perl 5.8.2 seems fine without this require, so
maybe it's older versions which are picky.
