apache2已经包含mod_ssl了，它的documents里面有关于mod_ssl的faq，照着做就行了，不难。

#
# autoconf 2.52 creates scripts that are incompatible with the Posix
# shell implementation (/bin/sh) on FreeBSD. Be sure to use v2.13
# of autoconf.
#
# Threaded MPMs are not supported on FreeBSD 4.x. Current releases of
# FreeBSD 5.x (5.2 or later) support threaded MPMs correctly. You must pass
# '--enable-threads=yes' to APR's configure in order to enable threads.
# Additionally, you must use libthr or libkse via libmap.conf as the default
# libc_r is still broken as of this writing. Please consult the man page for
# libmap.conf for more details about configuring libthr or libkse.

# Notice: Please updating to stable Apache 2.0 release:
# The two anoncvs servers currently available are:
# :pserver:[e-mail]:/home/cvspublic
# and
# :pserver:[e-mail]:/cvs/apache
# Choose one of these values for your setting of CVSROOT.
# Once you have set your CVSROOT, you need to log in:
#
# The password is "anoncvs" (without the quotation marks) for
# both servers

CVSROOT=:pserver:[e-mail]:/home/cvspublic

进入apache2 的ports，直接make install clean就可以了，已经包含mod_ssl了，安装完后，可以打入 http://网站名字/manual/ 来看apache2 的手册，如果装了mod_php的话，用phpinfo()也是可以看到关于mod_ssl的。
