```

Start by running Pkg.build("PyCall") and inspect deps/build.log, deps/build.jl, deps/buildutils.jl, and find_libpython.py around the failed Python spawn. Trace why the reported Temp\python.exe command cannot run on this Windows setup; done means PyCall builds successfully and using PyCall no longer fails during precompilation.
