Debian is key word.

Libtool is patched, not FSF.

This does not make sense. With and without  new dtags result will be the 
same.

It is long history It starts with 1* (1.5) libtool . Libtool 1.5 has 
some issues with multiple dependent libraries (more then two).
From debian was proposed a patch related to library dependencies. 
Unfortunately patch break existing regression test. From debian never 
was proposed version that pass regression test.

Libtool 2.0 fixes his issues related to multiple libraries. On the same 
Debian did not stop to contribute patch that breaks libtool.

As result when I decide to build something from source always to updated 
sources to FSF version.

So the right question is did reporter test with FSF version?
