Almost right. :)
branch-1-5: ltmain.in -> ltmain.sh -> libtool
branch-2-0/HEAD: config/ltmain.m4sh -> config/ltmain.sh -> libtool.

Please update to at least 1.5.14.

This description is, umm, well, a description. Not precise enough to do
anything.

We should look into using some DESTDIR-like information at link time to
override this. Noone has volunteered for auditing libtool for this yet,
the patches I've seen so far have done only patchwork.

Use --debug. Set
LIBTOOLFLAGS=--debug
when using a recent Automake. Note that branch-2-0/HEAD Libtool have
slightly better `set -x' support for ksh's.

Yes, acknowledged. Libtool solves a number of quite intricate problems,
though.
