You should talk with the libtool maintainer about libtool.

Regarding the pkg-config stuff: you just have to determine which libs
are direct and which are indirect deps for a specific port, move the
indirect one into Libs.private, and then convince the upstream
maintainers to pick up this change.

Bye,
Alexander.

Ah, you were all waiting for me to talk to libtool maintainer, you could
tell me before :-)

These are all "simple" steps. You haven't answered to "What prevents us
in doing it?" If we haven't already done it, I bet there is a reason.

Correct, sorry about not tellung you before. :)

I can tell you that he will not accept local modifications, which more
or less comes down to testing it yourself and let others test it too,
and then to convince the libtool authors to include it (maybe there is
something we are not aware about, which prevents this).

The subset of people which knew about the problem before was very
small (me and IIRC pav@, maybe others too I do not know about). The
subset of people which have time and interest to do something about
this was the empty subset...

Now the number of people which know about it is bigger. Time will tell
if the subset of people which do something about it is non-empty now...

Bye,
Alexander.

I think the first step could be to run a tinderbox build with a patched
libtool and see if anything break. Then, if the patch is simple, we
could add a target to patch ports using bundled libtool and see again if
anything break on tinderbox. What do you think?

I found some message I exchanged on the libtool list regarding this in
2007. I do not know the current state (libtool 2.2.6b) of this, but
someone with a little bit of time can check via the testcase which is
described in the mail at:
http://thread.gmane.org/gmane.comp.gnu.libtool.general/8500/focus=8501

When this testcase does not rise a problem, your approach sounds good.

Bye,
Alexander.
