You probably failed to run `emerge --sync`. dev-python/bpython-0.9.5.2 obviously does support installation for multiple Python versions.

And I would guess there is not a newer version than the one that came out less than a week ago: # $Header: /var/cvsroot/gentoo-x86/dev-python/bpython/bpython-0.9.5.2.ebuild,v 1.1 2009/10/02 01:51:18 arfrever Exp $ > dev-python/bpython-0.9.5.2 obviously does support installation for multiple > Python versions. > No. It obviously _doesn't_ support installation for multiple Python versions as you can see from the output I pasted above.

Maybe you use an overlay with older version of python.eclass which overrides python.eclass from the main tree. Post the output of `emerge --sync`.
(In reply to comment #4) > > It was fixed in python.eclass, not in dev-python/bpython. Okay. Does this mean that what I was told in the dev channel is incorrect?

What would I need to check for in the overlay. I currently have only one package there. > Post the output of `emerge --sync`. > See attachment. Thanks, Sol

Yes. I already explained to Tommy[D] that he was wrong. > What does the SUPPORT_PYTHON_ABIS variable do exactly? It tells that given package supports installation for multiple versions of Python, but it doesn't tell which versions of Python are supported. (This variable also doesn't need to be set in EAPI >= 3. The behavior enabled by this variable or EAPI >= 3 cannot be automatically enabled for all packages, because it usually requires small changes in ebuilds, and the absence of these changes would cause installation failures of some packages. The changes are performed by maintainers during conversion of ebuilds to support installation for multiple Python versions.) > > Maybe you use an overlay with older version of python.eclass which > > overrides python.eclass from the main tree. > > What would I need to check for in the overlay.

Is this patch available in a more recent version of portage? It appears as though all the more recent versions are hard-masked for me. Thanks for the fix!
Comment on attachment 206657 [details, diff] python.eclass.patch This patch was never committed. This problem is properly fixed in Portage 2.1.7.1.
