I am in the midst of writing a test for standalone libltdl for
HEAD... I should backport it to the release branch when I have
it working.  LT_WITH_LTDL treats the libltdl subdirectory as a
subproject that it wants to configure using ltdl/configure.ac.
You will need to add ltdl to SUBDIRS in you top Makefile.am too.

Please keep notes on your tribulations so that we can beef up
the documentation to cover anything you are confused by.

Cheers,
        Gary.
