>Description:
not sure if these two items are related. attempt to determine installed make version:

/usr/bin/make --version
cd: can't cd to ..
cd: can't cd to ..
cd: can't cd to ..
...{forever}

that seems broken, it was installed with:
URL_ROOT="https://cdn.netbsd.org/pub";
URL_BASE="NetBSD/NetBSD-$(uname -r)/$(uname -m)/binary/sets"
URL_COMP="${URL_ROOT}/${URL_BASE}/comp.tar.xz"
DIST_PATH="/usr/local/dist/${URL_BASE}"
mkdir -p "$DIST_PATH"
ftp -o "${DIST_PATH}/comp.tar.xz" "${URL_COMP}" \
  && tar -C / -xzf "${DIST_PATH}/comp.tar.xz"

the broken make (?) was discovered researching failure to build:
pkgsrc-2023Q4
../../devel/rcs

bmake clean clean-depends package

>How-To-Repeat:
LOCALBASE and cvs checkout are on nfs
fresh bootstrap, default mk.conf, cd devel/rcs
bmake clean clean-depends package

devel/rcs is building fine with NetBSD 9.3 pkgsrc-2023Q4
many packages are building fine with 10.0_RC2 pkgsrc-2023Q4
