This patch should fix issue https://git.blender.org/gitweb/gitweb.cgi/blender.git/commitdiff/9258b70453df3c806ea4d056217d6be7767c4a9a
I can confirm that the patch from https://bugs.gentoo.org/764563#c8 fixes the issue with missing XPending symbols for both v2.91.0 and v2.91.2, but compilation still fails later with more missing symbols from X11 libs: ------ /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: lib/libbf_intern_ghost.a(GHOST_DisplayManagerX11.cpp.o): in function `GHOST_DisplayManagerX11::getNumDisplaySettings(unsigned char, int&) const [clone .localalias]': GHOST_DisplayManagerX11.cpp:(.text._ZNK23GHOST_DisplayManagerX1121getNumDisplaySettingsEhRi+0x3c): undefined reference to `XF86VidModeQueryVersion' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: GHOST_DisplayManagerX11.cpp:(.text._ZNK23GHOST_DisplayManagerX1121getNumDisplaySettingsEhRi+0x5c): undefined reference to `XF86VidModeGetAllModeLines' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: lib/libbf_intern_ghost.a(GHOST_DisplayManagerX11.cpp.o): in function `GHOST_DisplayManagerX11::getDisplaySetting(unsigned char, int, GHOST_DisplaySetting&) const [clone .localalias]': GHOST_DisplayManagerX11.cpp:(.text._ZNK23GHOST_DisplayManagerX1117getDisplaySettingEhiR20GHOST_DisplaySetting+0x42): undefined reference to `XF86VidModeQueryVersion' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: GHOST_DisplayManagerX11.cpp:(.text._ZNK23GHOST_DisplayManagerX1117getDisplaySettingEhiR20GHOST_DisplaySetting+0xdc): undefined reference to `XF86VidModeGetAllModeLines' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: lib/libbf_intern_ghost.a(GHOST_DisplayManagerX11.cpp.o): in function `GHOST_DisplayManagerX11::setCurrentDisplaySetting(unsigned char, GHOST_DisplaySetting const&) [clone .localalias]': GHOST_DisplayManagerX11.cpp:(.text._ZN23GHOST_DisplayManagerX1124setCurrentDisplaySettingEhRK20GHOST_DisplaySetting+0x51): undefined reference to `XF86VidModeQueryVersion' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: GHOST_DisplayManagerX11.cpp:(.text._ZN23GHOST_DisplayManagerX1124setCurrentDisplaySettingEhRK20GHOST_DisplaySetting+0x6e): undefined reference to `XF86VidModeGetAllModeLines' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: GHOST_DisplayManagerX11.cpp:(.text._ZN23GHOST_DisplayManagerX1124setCurrentDisplaySettingEhRK20GHOST_DisplaySetting+0x103): undefined reference to `XF86VidModeSwitchToMode' /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: GHOST_DisplayManagerX11.cpp:(.text._ZN23GHOST_DisplayManagerX1124setCurrentDisplaySettingEhRK20GHOST_DisplaySetting+0x112): undefined reference to `XF86VidModeSetViewPort' collect2: error: ld returned 1 exit status ninja: build stopped: subcommand failed. ------ NOTE: Package x11-libs/libXxf86vm provides the XF86VidMode* symbols, and Blender's build system handles them in /var/tmp/portage/media-gfx/blender-2.91.2/work/blender-2.91.2/build_files/cmake/platform/platform_unix.cmake but fails to properly detect them during the configure phase (after all, there are not CMake's macros detection for the x11-libs/libXxf86vm libs anywhere in any CMakeLists.txt), thus leading to the aforementioned linking failures.
Fixed already in https://github.com/gentoo/gentoo/pull/20565. See the work in: bug 795003 bug 778008 bug 774372 bug 673422 bug 737388
