>Description:
        Try to build ffmpeg and see this:

===> do-bin-install [ffmpeg-20080727nb4, vlc-0.9.2nb1] ===> Binary install for 
ffmpeg>=20080727
=> Installing ffmpeg>=20080727 from /pkg_comp/packages/All;no/such/directory/All
pkg_add: could not process directory
pkg_add: no pkg found for 'ffmpeg>=20080727', sorry.
pkg_add: 1 package addition failed
=> No binary package found for ffmpeg>=20080727; installing from source.
=> Bootstrap dependency digest>=20010302: found digest-20080510
===> configure-message [ffmpeg-20080727nb4, vlc-0.9.2nb1] ===> Configuring for 
ffmpeg-20080727nb4
=> Replacing Perl interpreter in doc/texi2pod.pl.
=> Checking for portability problems in extracted files
Error, no memalign() but SSE enabled, disable it or use --enable-memalign-hack.
If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-user%mplayerhq.hu@localhost mailing list or IRC #ffmpeg on 
irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
*** Error code 1

        This is not the whole config.err file but a fragment:

>How-To-Repeat:
        see above
>Fix:
        Possibly CONFIGURE_ARGS += --enable-memalign-hack

        or possibly to extend this section from the makefile to x86_64:

# Doesn't work without memalign and memalign looks buggy.
.if !empty(MACHINE_ARCH:Mi386)
CONFIGURE_ARGS+=        --disable-mmx \
                        --disable-mmx2 \
                        --disable-ssse3
.endif

        I tried the latter, and it compiles, but I have not run it yet.

        Looking at the configure script, another possibility presents itself:
        add "disable need_memalign", like is done for freebsd and openbsd,
        and also remove the above CONFIGURE_ARGS additions:

    netbsd)
        oss_demuxer_extralibs="-lossaudio"
        oss_muxer_extralibs="-lossaudio"
        ;;
    openbsd)
        disable need_memalign
        LIBOBJFLAGS='$(PIC)'
        SHFLAGS='-shared'
        SLIBNAME='$(SLIBPREF)$(FULLNAME)$(SLIBSUF).$(LIBVERSION)'
        SLIBNAME_WITH_VERSION='$(SLIBNAME)'
        SLIBNAME_WITH_MAJOR='$(SLIBNAME)'
        oss_demuxer_extralibs="-lossaudio"
        oss_muxer_extralibs="-lossaudio"
        ;;
    freebsd)
        disable need_memalign
        ;;

    The memalign hack in libavutil/mem.c doesn't look buggy to me, but
    perhaps the formula could have written a bit clearer. It should
    use intptr_t instead of long, but since only the rightmost bits of
    the values are relevant, it doesn't matter much.
