Portupgrade Update

[Bob Perry]

I ran pkg_info after upgrading the ports tree and found two versions of 
the same package, imake-4.2.0_1 and imake-4.3.0.  I was about to 
deinstall the earlier version but first wanted to check the package 
requirements with the pkg_info -rR command.  The ouput indicated that 
imake-4.2.0_1 was required by 95 packages in my system.  Twenty-one of 
these packages also appeared in output I received after running the same 
command on imake-4.3.0. 
My packages were over 90% current.  I expected to see only one package 
requiring the older version.  Can anyone help me make sense of this?

Thanks,
Bob
