As root:
# portmaster www/chromium \ java/openjdk6 \ java/icedtea-web \ www/nspluginwrapper \ www/linux-f10-flashplugin10
Then:
# mkdir -p /usr/local/share/chromium/plugins
# ln -s /usr/local/lib/IcedTeaPlugin.so /usr/local/share/chromium/plugins/
# ln -s /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so \ /usr/local/lib/browser_plugins/
The Linux process file system, linprocfs(5) has to be mounted on /compat/linux/proc:
# mount -t linprocfs linproc /compat/linux/proc
To mount the proc fs at each system boot, in /etc/fstab, have:
1 | linproc /compat/linux/proc linprocfs rw 0 0 |
As a user:
