If it helps, here is my .kerlc file:
$ cat ~/.kerlrc
KERL_CONFIGURE_OPTIONS="--disable-debug --disable-silent-rules --without-javac --enable-shared-zlib --enable-dynamic-ssl-lib --enable-hipe --enable-sctp --enable-smp-support --enable-threads --enable-kernel-poll --enable-wx --enable-darwin-64bit"
KERL_DEFAULT_INSTALL_DIR=/Users/jose/.kerl/installs
If you run erl and paste here the beginning of the output, we will have an idea of what is enabled and not in your machine. IIRC, compiling Erlang without those flags is at least twice slower in my machine.
