Huge system slowdown while installing ports

[Jeff Singleton]

Just a shot in the dark ... but are you running Intego Virus Barrier
X6? Or one of Intego's other security apps?

If you are ... make sure to add your Macports folder to the exempt (Do
not Scan in Real Time) list....as Realtime monitoring from Intego will
cause exactly the issues you are stating.  It seems to do exactly as
it advertises and scans every file, every time it is
touched/accessed....I ended up turning off Real Time monitoring and
just run scheduled scans/updates.

You may just have had a bucketload of outdated ports that needed to be updated and it just took awhile. 13.5 hours still sounds like a lot to me, but I didn't see the whole list of ports that were outdated so I don't know.
