1 packages to be installed: thunderbird10-10.0.10 (116M to download, 0B to 
install)

proceed ? [Y/n] 
>How-To-Repeat:
prepare a binary package repository with firefox/thunderbird10.0.10 and an 
earlier centiversion of it. pkgin will prefer the earlier version unless
forced to use 10.0.10.

>Fix:
Unknown... Guess (but pure speculation - I didn't read the code):
Maybe use pkgtools' generic decimal comparison routines instead of it's own?
