hi arnold, this is how it looks like, when i run scons configure && scons:

nowhiskey@email-addr-hidden:~/software/nove/jackmix/jackmix-0.3$ scons
scons: Reading SConscript files ...
Checking for jack...(cached) yes
scons: done reading SConscript files.
scons: Building targets ...
g++ -o jackmix/jackmix jackmix/main.o jackmix/mainwindow.o -Llibgui
-Llibelements -Llibcore -Llibmatrix -Lbackend -L/usr/share/qt4/lib
-ljackmix_backend -ljackmix_core -ljackmix_mixingmatrix
-ljackmix_mixingelements -ljackmix_gui -lQtCore -lQtGui -lQtXml
-l-L/usr/local/lib -ljack -lpthread -lrt
/usr/bin/ld: cannot find -l-L/usr/local/lib
collect2: ld returned 1 exit status
scons: *** [jackmix/jackmix] Error 1
scons: building terminated because of errors.
nowhiskey@email-addr-hidden:~/software/nove/jackmix/jackmix-0.3$

and this is how it (does not) works, after applying the patch from lars
with patch -p1:

looks both the same...

i was not, i wanted to copy the content from /usr/local/share/autoconf
into /usr/bin/auticinf ad to remove the loclal one, creating an symlink
which shows to /usr/share/autoconf, but than i removed the wrong one.

i think, for a newbee the things gets only worse, when he gets some
routine in it!

cheers,
