libtool: Version mismatch error. This is libtool 2.2.4, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.4
libtool: and run autoconf again.

make[1]: *** [all] Error 2
make: *** [external/libbacktrace.a] Error 2
rm external/libwally-core/src/secp256k1/libsecp256k1.la

any idea how to proceed?
