^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
P.S. using strace and running   systools:make_script("start_ssl_clean")
shows error

stat64("/usr/local/lib/erlang/lib/ssl-3.0.4/src/ssl_pkix_oid.erl", 0xbfffeadc) = -1 ENOENT (No such file or directory)

After I symlink the .erl files from ... /ssl-3.0.4/pkix/   to ... /ssl-3.0.4/src/  directory
then systools:make_script() worked without the problems of not finding source code.

contents of start_ssl_clean.rel:
{release, {"OTP  APN 181 01","R10B"}, {erts, "5.4.2.3"},
 [{kernel,"2.10.3"},
  {stdlib,"1.13.3"},
  {ssl,"3.0.4"}]}.
