Thanks jan,
I agree regarding tcl/tk, having both versions is a pain. In the past i have 
done
the same as you - that is remove them all, then recompile them from source into
/usr/local. Then do the same for blt. I think i might take that path again.

Catherine,
I am beginning to think that SuSE is trying to cover too many bases with the
gcc/egcs setup, as they do by having both tcltk 7.4.xx and 8.0.
I checked out the the directory structure on SuSE.6.1.
With the `gnobjc' and `gobjc' RPMs installed :
/usr/lib/gcc-lib/i486-linux/egcs-2.91.66 contains :

cc1obj        f771          libg++.a      libg2c.a      libstdc++.a
cc1plus       include/       libg++.so     libobjc.a     libstdc++.so

the /usr/lib/gcc-lib/i486-linux/egcs-2.91.66/include dir has a subdir objc/
containing :

NXConstStr.h   encoding.h     objc-list.h    thr.h
Object.h       hash.h         objc.h         typedstream.h
Protocol.h     objc-api.h     sarray.h

I have just left the c++ stuff as the egcs compile replaces everything else.

Now, using
./configure --with-bltdir=/usr/X11R6 --with-pngdir=/usr/X11R6 --host=i586-linux
the Swarm compile errors are: --- OH DEAR --
