x11-libs/libXtst needs x11-proto/xextproto and x11-proto/inputproto or configure will fail. Reproducible: Always Steps to Reproduce: 1. emerge --depclean --with-bdeps n 2. emerge --oneshot libXtst 3. Actual Results: checking for XTST... configure: error: Package requirements (x11 xext recordproto xextproto inputproto) were not met. Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively you may set the XTST_CFLAGS and XTST_LIBS environment variables to avoid the need to call pkg-config. See the pkg-config man page for more details.

Not sure how xextproto managed to not be installed. libXext is in RDEPEND of libXtst, and xextproto is in RDEPEND of libXext. I did add inputproto, though.
