Sorry, I forgot about the fact that -u goes through all the  
dependencies and tries to _uninstall_ as well as upgrading them,  
which will of course fail as you observed when ports that depend on  
them are installed (I think this is a good thing to save oneself from  
unintended consequences).  One needs to add the -f flag to force it  
to uninstall ports even when they have there are ports installed that  
depend on them, and/or the -n flag to not upgrade dependencies of  
ports specified for upgrading (this saves multiple rebuilds of  
packages when outdated ports depend on the same package, as -u will  
otherwise rebuild it once for each such instance).  I usually run  
"port -ufn upgrade outdated" myself.  (See additional comment below.)

The reason I tend not to just run "port upgrade outdated" is that, as  
you've probably noticed, it leaves the older versions of the ports  
installed (though inactive); I suppose I'm comfortable with living on  
the edge a bit if it saves space on my laptop hard drive :-)

As for the failure to upgrade grace here, I'm guessing that the  
reason was that, at the time you ran "port upgrade outdated", you had  
the two versions of grace already installed and port thought it only  
had to activate the newer one (which failed because the older one was  
already active), whereas you had only one version installed of each  
of the other ports, and so it did deactivated the old one before  
installing the new one.  If this is what it did, then that looks to  
me like a bug.  If you (or others reading this) would be so kind as  
to try to reproduce and confirm this (and then file it as a bug if  
you do), or otherwise figure out what is happening, that would be  
most helpful.

> Btw, it would be nice to have "port upgrade -u" really work.

(See first comment above if you skipped it :-)

And thank you for your input to help us make it better!
