Mozilla 1.7 build hangs on atk

[Lars Eighner]

I am attempting to upgrade to Mozilla 1.7 from 1.6x.  Whether I use
portupgrade or not, it hangs on atk.

The build cannot tell when atk is installed, so whether atk is installed
or not, it attempts to make and install atk.  I have tried this every
which way I can think of, including:

rebuilding the package database
deinstalling atk before I start the mozilla build
upgading atk before I start the mozilla build (which does nothing
since the latest version is already installed (atk-1.4.1_2).

Still it is the same. Mozilla 1.7 build thinks atk is not installed
(whether it is or not) and attempts to install it, which stops
when atk is built and discovers it is already installed or
mozilla cannot find a shared library libatk-1.0.so.600.

atk-1.4.1_2 only has libatk-1.0.so.400, yet this is the version of
atk that the mozilla build thinks it wants.

Suggestions?
