Subject: [PATCH] * if libltdl fails to configure, abort the configure process.
  We don't have the   ability at this point to roll back and build without
 libltdl if we thought we   we going to have libltdl (we can configure without
 libltdl if we know from   the start it won't be there, from
 --disable-dlopen).

This commit was SVN r8336.
