или можно:

# C-Shell
$ setenv LANG C

Но чтобы понять с какими параметрами нужно компилировать, читаем README или документацию на официальном сайте, я приведу пару примеров сборки:

$ ./configure --prefix=/opt/local
$ make
$ make DESTDIR=/tmp/erlang-build install
$ cd /tmp/erlang-build/opt/local
$     # gnu-tar is used in this example
$ tar -zcf /home/captain/my-erlang-build.tgz *
$ su -
Password: *****
$ cd /opt/local
$ tar -zxf /home/me/my-erlang-build.tgz
