I tried to find out more about this issue. Looks like AC_LIB_LTDL got
deprecated somewhere between libtool 1.5 and 2.2. The older version didn't call
AC_CONFIG_SUBDIRS where the newer does. I couldn't get the savannah git web
frontend to display a "blame" version of the file, to see where the relevant
changes were introduced. The 2004-08-22 ChangeLog entry mentions the obsoletion
of AC_LIB_LTDL as part of the preparations for 2.0, but not much more.
http://git.savannah.gnu.org/gitweb/?p=libtool.git;a=blob;f=ChangeLog.2004;hb=HEAD

I see several possible approaches:

1. Conditionally have the ebuild remove AC_CONFIG_SUBDIRS from line 42 of
   configure.ac if libtool 2 is used
2. Move AC_CONFIG_SUBDIRS after AC_LIB_LTDL and wrap it in an m4 check whether
   the directory is already registered
3. Declare that functionality of known macros should not change within a slot
   and move the whole issue from gnunet to libtool maintainers

Keep in mind that 1. and 3. at the same time might be a bad idea. Also if
upstream should decide something like 3. and remove the AC_CONFIG_SUBDIRS
again, then the ebuild would need to be fixed over again.

Could you file a bug upstream?

Upstream applied a fix, which we might wish to include in order to fix this:
svn diff -r6742:6836 https://gnunet.org/svn/GNUnet/configure.ac

I also wrote to the libtool mailing list, without reply so far:
http://thread.gmane.org/gmane.comp.gnu.libtool.general/9323

Created an attachment (id=156589) [details]
Upstream fix -r6742:6836

Please apply this patch in the ebuild, in order to fix this issue.

Applied, thanks!
