When building rpm with the python use flag enabled it finds a temporary python instance (actually a shared link) in "/var/tmp/portage/app-arch/rpm-4.11.1/temp/python2.7/bin/python" which is then used in the resulting binaries and causes runtime issues later.

If I run the following command using the Fedora Kernel RPM specfile: # rpm -q --specfile kernel.spec sh: /var/tmp/portage/app-arch/rpm-4.11.1/temp/python2.7/bin/python: No such file or directory {...following output trimmed...}
More simple reproducer: $ rpm --eval '%{__python}' /var/tmp/portage/app-arch/rpm-4.11.1/temp/python2.7/bin/python %__python macro is set incorrectly and this can be triggered with some spec files (basically any python spec following Fedora guidelines)
Note that as a workaround for now you can manually fix /usr/libexec/rpm/macros if required. While we could simply fix up the macro to be /usr/bin/python that might be incorrect from RPM perspective (which generally has separate macro for python 3.x). It would most likely only cause issues if people actually tried to build rpms for different distributions on Gentoo. There are probably more related issues if that would be the goal.

Any progress on resolving this? Manually fixing the macros file after each upgrade of the rpm package is getting tiring.
So I've committed rpm-4.11.2-r1 which contains a hardcoded /usr/bin/python2 instead of dynamic @__PYTHON@. I think it generally makes sense even for spec files coming from RPM distributions but I wouldn't bet on it :-) Closing, thanks for patience :-)
