Everything else is fine, including 10.6 PowerPC, but 10.6 Intel broken:

It’s perhaps it builds a bunch of stuff downloading it from GitHub, and there CMakeLists are written without any idea to respect environment settings or borrow those from master project.

Do we have a mechanism to deal with such issues? Besides of manual patching.

[kencu (Ken)]

one simpler thing to try would be to set the build environment envvars to match the configure environment envvars.

the subprojects are configuring during the build phase, but the environment is not fully set up then, so they are configuring with a number of defaults, like the compiler
