I cannot build pypy3 from source because it takes too long on my old hardware. But I found that there is a binary package for it. I tried installing portage with pypy3 target, but it does not support sqlite, so I had to disable sqlite metadata cache module. And without it (but with pypy3) portage takes about 2 times longer to calculate dependencies, so it does not make sense using pypy3. It would be great if pypy3-exe-bin was built with sqlite support. Reproducible: Always
PyPy3's sqlite support is via CFFI, and it should be entirely independent of pypy-exe vs pypy-exe-bin. Do you have USE=sqlite enabled on dev-python/pypy?
Okay. For some reason I thought I saw this flag on dev-python/pypy3-exe package, not on dev-python/pypy3. Oh well.
