Looks like kis_png_converter.cc needs patching. I'll see if I can figure it
out based on the gwenview patch. I think that is all it needs. If anyone is
good with this and can beat me to it, my hat is off to you.
And wow - processor speed really makes a huge difference in build times. For
the packages I'm building on arch:
i686 build - old p4 2800
Build time 462 min. ~ 7.7 hours
x86_64 build - newer (but old) 9850 X4
Build time 224 min. ~ 3.7 hours
Never really built projects this large before, but speed -- does matter :)

koffice was building perfectly -- until it hit:
Yeah. Been there done that. :) I submitted a bug report to split the koffice package into
smaller modules.

There was a patch to that same file 2012-01-11. I suspect the libpng 1.5 changes require a
similar change.

Yes, speed is good for development but bad for users. Developers get accustomed to their
scream demons and then forget to test on older hardware.
I have tried several times to use ccache to improve build times, but I never have gotten
that process to work for me. I want to try distcc because I have two dual core machines
here. I'm just not sure I want to burn the extra wattage.
If your new system is multi-core then use parallel processing. The general guideline is
NUM_CORES + 1. I have a dual core and set NUMJOBS=-j3. My build scripts then run make
$NUMJOBS.
Check the wiki but I believe only two packages fail to build with parallel processing:
tdebindings and tdemultimedia.

Darrell, David,
Number of cores tends to perform better -j4 for 4 cores. The +1 thing has
been disputed numerous times :)

What an analogy! :)

Darrell, David,

It also depends on hyperthreading, available memory, cache sizes, the
cache-friendliness of the compiler (GCC really isn't cache-friendly at
all) and a lot of other things.
On my hyperthreaded quad-core 2009-vintage Nehalem (256Kb K2 cache, 8Mb
shared L3 cache), I benchmarked GCC 4.5 as taking least time with -j 12
(for a sizeable parallelizable compilation). But it has a hardware RAID
array and 24Gb RAM, so it could easily keep up with those demands.

That will be fun :) The 64 bit box is quad core so I'll try 5 :)
