Comment 2 for bug 1001912

please keep the change for now. it's important to catch all this kind build failures early in the cycle. There should be invalid uses of pyshared during build time, and then maybe build failures during the install stage when install files reference pyshared.

There is nothing in policy which explicitly allows the use of pyshared for anything besides installation.

Please let's collect these issues and tag them with `pyshared'.
