--- Comment #5 from jimis <jimis at gmx dot net> 2011-08-03 19:32:09 UTC --- DESTDIR is supported just fine, but it is not prefix, it serves different purposes. In particular it installs in /$DESTDIR/$prefix but installed package would search libraries in /$prefix. joseph: Thanks for pointing me to that bug, hopefully this will be fixed in libtool, it's much needed functionality at least for me.
