X won't upgrade in portupgrade of expat2

[Christian Hofer]

Hi,

I cvsup'ed my ports yesterday and just had to upgrade expat, following 
the instructions in /usr/ports/UPDATING.

But when I try

portupgrade -rf textproc/expat2

my computer starts compiling a lot of things and after a while gives 
back the error, that X could not be updated (thus: 1 package failed, 70 
or so skipped). Until now, everything still works fine, (or better: 
Thunderbird is working again after portupgrading expat) but I'm still 
worried what the error means.

Thank you for your help,
Chris
