I timed the build of OpenOffice on Gentoo yesturday using the following 
command:

time emerge -Du openoffice

The build of version OpenOffice 1.0.3-r1 completed today and time spit out 
the following:

real    844m6.053s
user    704m12.660s
sys     31m30.340s

Overall, the build of OpenOffice on my system (Athlon 900 MHz) took 14 hours 
4 minutes and 6.053 seconds.

I would think a good way to determine how long a build will take on your 
system is to divide a bogomips seconds factor by the bogomips from 
/proc/cpuinfo ( x / bogomips = time ) then throw in a fudge factor of 10%.  
Any thoughts anyone?

The bogomips seconds factor could be determined by compiling OpenOffice on 
several systems using the time command to record the amount of time it 
takes, calculating the bogomips seconds factor for each system using the 
formula "time * bogomips = x" and then averaging the numbers.

On my system, the bogomips are 1782.57 so the bogomips seconds factor for 
OpenOffice would be 50646.053 seconds * 1782.57 bogomips = 90280134.6962 
bogomips seconds.

Using the bogomips seconds factor from above, my laptop should take 
90280134.6962 bogomips seconds / 730.72 bogomips = 123549.5602 seconds (34 
hours 19 minutes and 9.5602 seconds) +- 10%.  I'll find out how long it 
actually takes sometime in the next week because I'm currently updating 
Gentoo on it.
