Wookey, Well, after some search, I found an old post about "old debian problem... need to link/usr/include/tcl8.3/tcl.h to /usr/include/tcl.h" So I did:
ganbo:/home/tatel# ln -s /usr/include/tcl8.4/tk.h /usr/include/ ganbo:/home/tatel# ln -s /usr/include/tcl8.4/tcl.h /usr/include/ ganbo:/home/tatel# ln -s /usr/include/tcl8.4/tclDecls.h /usr/include/ ganbo:/home/tatel# ln -s /usr/include/tcl8.4/tclPlatDecls.h ganbo:/home/tatel# ln -s /usr/include/tcl8.4/tkDecls.h And it worked... partially: compilation ran with no errors, but I still can't get the model viewer window; trying to see what other thing could I have missed just now. GL messages were efectively about not having installed xlibmesa-dev BTW, on my "regular" woody box with TclTk8.3, there are not soft links and it works fine, so probably there is a difference from the backported package 8.4 and 8.3 stable Hope this helps, Roman
