From what I understand I have my flags set up such that vim build build against Python 3.6, however when I run vim it seems to be built agains Python 3.7: ``` # equery u vim [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for app-editors/vim-8.1.1846: U I - - X : Link console vim against X11 libraries to enable title and clipboard features in xterm + + acl : Add support for Access Control Lists - - cscope : Enable cscope interface - - debug : Enable extra debug codepaths, like asserts and extra output.

Confirming this. After removing python3.6: !!! existing preserved libs: >>> package: dev-lang/python-3.6.10-r2 * - /usr/lib64/libpython3.6m.so.1.0 * used by /usr/bin/vim (app-editors/vim-8.2.0360) $ emerge -qpv app-editors/vim [ebuild R ] app-editors/vim-8.2.0360 USE="acl nls perl python -X -cscope -debug -gpm -lua -luajit -minimal -racket -ruby (-selinux) -sound -tcl -terminal -vim-pager" PYTHON_SINGLE_TARGET="python3_7 -python3_6 (-python3_8)"
I think the problem is: $(use_with python python3-command $(type -P $(eselect python show --python3)))

I encountered the same issue, only the other way around. My system was updated from python 3.6 to 3.7, but vim was still compiled with python3.6m, because of course I only change the eselect setting after the whole update was complete.
Sorry for the noise, but I just noticed this applies to vim and gvim separately. I need to recompile both to work around this issue.
