Now this is interesting and a lot more promising, but alas, does not work.
Doing a "make dist" gets me roughly this:

# make dist
{ test ! -d panzers-0.1 || { find panzers-0.1 -type d ! -perm -200 -exec
chmod u+w {} ';' && rm -fr panzers-0.1; }; }
mkdir panzers-0.1
list='src'; for subdir in $list; do \
  if test "$subdir" = .; then :; else \
    test -d panzers-0.1/$subdir \
    || mkdir panzers-0.1/$subdir \
    || exit 1; \
    (cd $subdir && \
      make  \
        top_distdir="." \
        distdir=../panzers-0.1/$subdir \
        distdir) \
      || exit 1; \
  fi; \
done
make[1]: Entering directory `/home/chakie/prog/c++/osg/panzers/src'
g++ -g -O2 -I/opt/osgSDL//include -I/usr//include    setup.cpp   -o setup
...


Same problem. The Makefile.am is definitely untabified now.

Am I a total idiot?
