sys-apps/fd-7.5.0 wants libjemalloc.so from the main OS (e.g. /usr/lib64/libjemalloc.so) because fd-7.5.0.ebuild contains ${ESYSROOT} instead of ${EROOT}.

EROOT is not the correct fix, it is not to be used in src_compile: https://dev.gentoo.org/~ulm/pms/head/pms.html#x1-10900011.1. ESYSROOT seems like the correct variable here. It's prefixed and it is where DEPEND-category packages should be installed: https://dev.gentoo.org/~ulm/pms/head/pms.html#x1-720008.1.
JEMALLOC_OVERRIDE=/usr/lib64/libjemalloc.so seems to suggest ESYSROOT is not set, is the ebuild using a correct EAPI?
