As Kevin said, not a problem - ignore those warnings. It's a well-known deficiency in dpkg-deb.

Could you make these packages available to me, so that I can put them in the repository? Thanks.

Well, I guess it did, otherwise it shouldn't build :-)

Try unsetting the ROOTSYS environment variable (and LD_LIBRARY_PATH for that matter). These variables are _not_ needed.

This could be a problem with the Qt GUI stuff in ROOT. I may be wrong, but I think `TRootCanvas' isn't what should be used in for making the canvas when you want Qt widgets. Hopefully Valeri Fine has something to say about this.

Oh, ok. Thanks. They have been posted. Thanks again.
