The NetBSD Foundation
>Environment:
>Description:
misc/libreoffice apparently depends on gcc12:

# configure script checks the version of GCC.
GCC_REQD+=      12

This means it will not work on any NetBSD release without risking shared library collisions, since the newest that NetBSD ships with is gcc10.  This is not viable.
>How-To-Repeat:
build misc/libreoffice on any NetBSD release
>Fix:
Various options:

1. Revert to an older libreoffice branch.
2. Fix the configure script.
3. Rename all the gcc C++ libraries so that there is no risk of collision with base.
