Hi Charles,

Thanks for the bug report.

AFAICS, this can only happen if libltdl was treated with automake-1.9
and the tests run with automake-1.10 in place, so that the toplevel
package (named subproject-demo-2.1a) is treated with 1.10.

Hmm.  This is kind of a backward incompatibility, unfortunately.
It can be helped by using the same Automake version for both
bootstrapping and testing, or by using 1.10 for libltdl.

Alexandre said he did not want to continue 1.9.  If there were to be
another point release, this patch would certainly be a good candidate
IMHO.  For reference, below's the patch including ChangeLog entry.


2007-03-26  Charles Wilson  <...>

        * lib/am/ (distdir): Do not fail if $(distdir) already
        exists, for forward compatibility with Automake 1.10 that
        overrides the removal due to $(am__remove_distdir).  Fixes `make
        dist' failures in which the toplevel package uses 1.10, but a
        subpackage 1.9 only.
