Based on how the VMs were provisioned when Ryan reported the problem, I do not see any obvious pattern to suggest it was the physical hardware. I recommend trying to rebuild php and a couple other larger ports to see if this reproduces and is not php-specific. 

Just to follow up, this is still happening.

Today's data from updating php54 to 5.4.21 and php55 to 5.5.5 in r112341:

lion: 2 hrs, 15 mins, 26 secs

Time for building just the php55 subport:

I looked through some other recent builds and found a similar situation when kdevplatform was updated to 1.5.1 in r112336:


snowleopard: 15 mins, 21 secs (build phase 3 mins, 25 secs)
