Sometimes dev-python/pympler-0.3.1 builds & sometimes is does not. When it does not, it fails with : error: can't copy 'pympler/__init__.py': doesn't exist or not a regular file : with multiple reference to environment. Posting build.log & environment. * Re-running an emerge or using MAKEOPTS="-j1" works more often than not. BUT if almost always fails during @world pass. Saw a request for stable, hope this helps out. Reproducible: Always
