After upgrading to sdl-1.2.15-x86_64-1 I get failed: /usr/lib64/ undefined symbol: _XGetRequest

Specifically when running /opt/VirtualBox/
Whole error is:
VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/opt/VirtualBox/",) failed: /usr/lib64/ undefined symbol: _XGetRequest

Sure enough:
# objdump -T /usr/lib64/ |grep XGetRe
0000000000000000 DF *UND* 0000000000000000 _XGetRequest

sdl-1.2.15-x86_64-1.txz (from slackware64-current)
/usr/lib64/ -> (Not work)

sdl-1.2.14-x86_64-5.txz (from slackware64-14.0)
/usr/lib64/ -> (works)

Is sdl-1.2.15 missing something?

fskmh@workstation:/usr/local/src/SDL-1.2.15> grep -r XGetReq
src/video/x11/SDL_x11sym.h: * libX11 added _XGetRequest, and macros use it behind the scenes.

src/video/x11/SDL_x11dyn.c:                    p_XGetRequest = SDL_XGetRequest_workaround;

Looks like this symbol comes from libX11, and libSDL definitely links to it:

        /lib64/ (0x00007f599f744000)

On my slack64-current, libX11-1.5.0 appears to originate from Slackware 14 release.

Thanks to fskmh. That lead me on the right track of upgrading libX11, and others while at it. Didn't even think of it as I don't run X locally, only over SSH.
Now I know how to trace lib dependencies more.
