I tried to build openoffice 1.0.1 but the build failed because the libstdc++.so.5.0.0 was missing in the solver/641/unxlngi4.pro/lib was missing. Instead, the lib was build as the 5.0.1 version. As a workaround, I linked the 5.0.1 lib to be the 5.0.0 and the build continued. Since I am still building I don't know wheter it will build correctly, but I do not expect any problems with it.
fixed in 1.0.1-r3
