Hi there,
I have SN 10.6.1 with kernel and Fink set to 64 bits.
All has been installing beautifully so far and I am even taking further.
For example, for packages that asked for dependencies on openmotif3, I
simply changed that for openmotif4 in their respective *.info files.
For example, I did it for tetex.info and it installed and worked nicely.
So I am recommending to the maintainer of tetex packages, in particular, and
to others maintainers that have references to openmotif3, to review their
*.info files and test it obviously.
I suggested that for molmol.info and I saw today that the maintainer updated
it for unstable. Molmol is working fine for me.
