Look, Frederic.  We may be able to explain what's going wrong, or
whether you will need to upgrade Libtool, and if you need to, how to
achieve this.  But before I can do that, I need to know more
information.  And I need *exactly* the information that I asked for, at
least; possibly more, but I will ask for that later then.  Also I ask
you not to try to upgrade the Libtool files in your package *just yet*,
because then your bug will be a moving target for me.  I cannot help you
if all you tell me is your guesswork.  Here's a good text to read:
<http://www.chiark.greenend.org.uk/~sgtatham/bugs.html>.

So please do exactly as I asked.  Post the complete output, and please
post to the bug-libtool list; this topic is not the right one for the
bug-autoconf list.  This is so that both I will be able to find this
discussion again two years from now, and that other users that have the
same problem but know that it's about Libtool, will be able to search
for it efficiently.

Here's what I asked last time, again:

>>Please report to the bug-libtool mailing list with the following

>>  ./libtool --config

>>Please also post the libtool link command that caused this output:

>>> jp2/.libs/libjp2.a jpc/.libs/libjpc.a jpg/.libs/libjpg.a mif/.libs/libmif.a
>>> pgx/.libs/libpgx.a pnm/.libs/libpnm.a ras/.libs/libras.a   -lm -ljpeg -lc

If you do not understand the above, don't hesitate to ask.

Hope that helps.

Cheers,
Ralf
