 Here's what I found:

 mozpack.errors.ErrorMessage: Error: Error while running startup cache precompilation

 I dug through the python code, and it looks like the problem is that the
 command that it says that it is "Executing" is failing.  If I try
 running this command manually, this is what I see:
 
 # /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/xpcshell -g /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/ -a /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/ -f ../../../toolkit/mozapps/installer/precompile_cache.js -e 'precompile_startupcache("resource://gre/");'
 Shared object "libicui18n.so.50" not found, required by "libxul.so"
 
 The problem is that xpcshell is loading a stale copy of libxul.so in
 /usr/local/lib/libxul that is looking for an old copy of libicui18n.so,
 which has undergone a library version bump since libxul was installed.
 
 ... or maybe not.  Looking back at the python script:
 
         if launcher.launch(['xpcshell', '-g', gre_path, '-a', app_path,
                             '-f', os.path.join(os.path.dirname(__file__),
                             'precompile_cache.js'),
                             '-e', 'precompile_startupcache("resource://%s/");'
                                   % resource],
                            extra_linker_path=gre_path,
                            extra_env={'MOZ_STARTUP_CACHE': cache}):
             errors.fatal('Error while running startup cache precompilation')
             return
 
 it looks like $LD_LIBRARY_PATH is getting set to
 /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/
 and $MOZ_STARTUP_CACHE is getting set to a temporary zip file under
 /tmp.  If I try to duplicate that:
 
 env MOZ_STARTUP_CACHE=/tmp/cache.zip LD_LIBRARY_PATH=/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/ /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/xpcshell -g /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/ -a /usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin/ -f ../../../toolkit/mozapps/installer/precompile_cache.js -e 'precompile_startupcache("resource://gre/");'
 Illegal instruction (core dumped)
 
 Running gdb on the core file gets me this backtrace:
