An empty directory in site-packages is a valid Python module, unfortunately, because of namespaces. If installing packages in parallel, the pythran module might "exist" but be empty (hence no __version__ attribute). Catch AttributeError to avoid a narrow race. This might still be a Portage issue if there's a substantial delay between creating the directory and installing the remaining files though. Thanks to Eli Schwartz for helping out. Bug: https://bugs.gentoo.org/902713 Signed-off-by: Sam James <sam@gentoo.org>
