Created attachment 294427 [details] Libreoffice processes tree while compiling At some point of the build, libreoffice-3.5.0.0 uses a wrong parallelization scheme, leading to very hi load : PC becomes near unusable (workload = 35 at peak in my case). Basically, when using MAKEOPTS=-jX, libreoffice uses X*X. Personally, I uses -j5, and I get arround 25 gcc processes ! The issue seems to be around a build.pl that forks 5 processes, each of one launches a dmake -P5... See attached a tree of the processes while building (extract from ps -auxf) And here is my emerge --info: Portage 2.2.0_alpha79 (default/linux/amd64/10.0/desktop, gcc-4.5.3, glibc-2.14.1-r1,

Yeah this is being fixed in the upstream repo rather than fixing it in our ebuild. WONTFIX for now, I really hope we will fix it prior release, if not everything using dmake would have to be compiled in one thread only which slows down a lot complete build.
