(you mean the installation via g.extension isn't functional on your machine)

Perfect. In any case, it will be in the next release.

No, it is the same...

You see that grass/gis.h is missing which should be there in your
binary installation in include/.
Ah I just realise that it looks in
/usr/src/packages/BUILD/grass-6.4.0RC6/dist.i686-pc-linux-gnu/include
which is unlikely to exist on your machine, right?

Yes but does /opt/grass/include/ contain anything? Does it have a subdirectory
grass/ with a series of .h files? This are needed and not found above since
there is something wrong with your paths.

The relevant compile line is
make MODULE_TOPDIR="$GISBASE"

so it should find /opt/grass/ but it doesn't. What reports

echo $GISBASE
in a GRASS session?

Is it possible that you have two GRASS version installed?
