Portupgrade stops at pango and atk due to gir-repository-*

[Jan Henrik Sylvester]

I tried to follow the steps in UPDATING, but portupgrade could not 
install pango and atk due to the presence of 
gir-repository-gtk20-0.6.5_3 and gir-repository-pango-0.6.5_3 (for which 
it reports necessary updates from 0.6.5_3 to 2.20.1 and 1.28.0 
respectively -- weird).

Is this a problem with portupgrade?

I did delete the two packages with all their dependencies to reinstall 
them after the portupgrade, but there is probably a better way.

Cheers,
