The ld-musl-x86_64.path contains all pathes and it is > read. So the question is: Why does libcurl.so.4 not find > libssl/libcrypto? Any insight? Is the ldd you're invoking a symlink to ldso? If so, that's deprecated usage which has problems using the right path (because the pathname comes from what was used to invoke ldd) and you should replace it with a shell script: #!/bin/sh exec /qlnx/lib/ld-musl-x86_64.so.1 --list "$@" Then ldso will have the right base pathname to look for its .path file relative to.
