Since 2.2.1 PyPy supports building libpypy-c.so shared library + small executable instead of one huge executable. Shared library is useful for embedding PyPy into other applications, e.g. uWSGI server. I think a "shared" USE flag should be added that would result in adding "--shared" option to the translator (rpython). Reproducible: Always
Does anything actually use this shared library?
It has been developed by someone from uWSGI as I understand. So I wanted to build uWSGI with PyPy but found out that there's no shared lib. Shared library support has appeared very recently but I think it won't hurt to have the USE flag around (and allow people like me to use it). I'll attach a patch for 2.3 that worked for me.
Created attachment 378752 [details, diff] patch that worked for me This patch worked for me. I bumped version to 2.3.1 because why not (although the source didn't appear at the expected URL). I'm not sure if LD_LIBRARY_PATH setting is good but I didn't come up with a better idea.
There's no need for an extra flag -- having the library built won't hurt. It would be better if it had proper SONAME though.

So tell upstream. *pypy-2.3.1 (18 Jun 2014) 18 Jun 2014; Ian Delaney <idella4@gentoo.org> +pypy-2.3.1.ebuild: bump; add shared lib libpypy-c, prompt and initial patch by Y. Taraday in bug #513014, closes said bug
Thanks, Ian!
