Default cmake-2.8.1 build problems

I'll likely just slog through a comparison, config file by config
file, to find the differences.


I would love to see the 3D scatter plot of "Time spent by Gentoo users
running revdep-rebuild (hrs)" vs. "Package updated" vs. "Date (2000-2010)".

I suspect there would be one HUGE blob in June 2010 where "libpng"
crosses the X axis.

I myself have spent at least an hour on each of the several machines
that I run.




The libpng upgrade cost me about 12 hours or so. Close to 11 for the
recompile, WITH NO GUI either. Auggggh.

Only one hour? You cheated!!!

And obviously you have forgotten all about expat-2 from way back when.....

Thanks for the idea Arttu. Your suggestion worked fine.

It does appear that this is just more libpng stuff so hopefully when I
get the machine fixed up I can remove the -qt4 flag and get it back
like it was.

I appreciate your help,
Mark
