>Description:
I've compiled port www/firefox (5.0, using the tarball from http://www.freebsd.org/cgi/cvsweb.cgi/ports/www/firefox/).  I noticed that the port requires 540993KB (as reported by "pkg_info -s firefox-5.0,1").  I also noticed that /usr/local/lib/libxul/sdk/lib/libxul.so has a size of 470816K (as reported by "ls -s /usr/local/lib/libxul/sdk/lib/libxul.so").  

I found that running "strip" on libxul.so brings it to 23328K.

I compiled the port (again) inside /usr/bin/script and found:

  sputnix# grep " -g" compile_firefox | grep " -O2" | wc -l
      2783
  sputnix# 

I suspect that compiling with both "-O2" and "-g" causes libxul.so to grow that large (as evidenced by the result of using strip on the lib).  I'm also not sure how much sense it makes to use "-g" to build the port.  By any means, the file /var/db/ports/firefox/options contains the line "WITHOUT_DEBUG=true", reflecting my choice when I compiled firefox for the first time.

The result of the compile session is availlable (5456k). The contents of the file /var/db/ports/firefox/options are:

# This file is auto-generated by 'make config'.
# No user-servicable parts inside!
# Options for firefox-5.0,1
_OPTIONS_READ=firefox-5.0,1
WITH_DBUS=true
WITHOUT_PGO=true
WITHOUT_SMB=true
WITHOUT_DEBUG=true
WITHOUT_LOGGING=true
WITH_OPTIMIZED_CFLAGS=true

>How-To-Repeat:
Get the tarball from http://www.freebsd.org/cgi/cvsweb.cgi/ports/www/firefox/,
untar it as /usr/ports/www/firefox/; go there and say "make install". Accept the suggested configuration (DBUS=true, PGO=true, SMB=true, DEBUG=false, LOGGING=true, OPTIMZE=true).

Observe a 470816K /usr/local/lib/libxul/sdk/lib/libxul.so
Observe that pkg_info -s firefox-5.0,1 reports a size of 540993KB for the port.
