After some messing around with the build scripts, I figured it out. This works for me: 0. Choose installation path for FFI -> $LIBFFI_PATH 1. Configure, build, install libffi: 1a. Download libffi from https://sourceware.org/libffi/ and untar it 1b. ./configure --prefix $LIBFFI_PATH 1c. make 1d. make install 2. Configure CPython: (I'm using tcsh syntax, it is slightly different with bash) 2a. setenv PKG_CONFIG_PATH $LIBFFI_PATH/lib/pkgconfig/ 2b. setenv LDFLAGS "-L $LIBFFI_PATH/lib64/" 2c. /configure --with-pydebug 3. Build 3a. setenv LD_LIBRARY_PATH "${LIBFFI_PATH}/lib64/" 3b. make -s -j2 Good luck! -- https://mail.python.org/mailman/listinfo/python-list
