The overhead of using VMware on Linux was in the area of 50%. On a 4
core machine, this made the build overall faster than running native.
At the time (smaller pkgsrc tree), the full build needed around 4 days
on a Dual Dual Core with 2GHz.

For comparision, a box I am currently borrowing for stress testing is
doing a full bulk build in 20h (Intel Dual Quadcore), under NetBSD
5.0RC2, including idle time due to running out of jobs.
