A regular user has no write access under /usr/local/lib/linux-tor-browser
where those commands are run. As the port moves TorBrowser/Data
to %%USERDATADIR%% the quoted path may need to be adjusted as well.

ticket#9353 probably doesn't affect linux-tor-browser because only
GTK_IM_MODULE=xim is supported due to lack of extra gtk immodules among
linux- ports. So, the quoted error about applying IBus workaround can be
ignored for now.

Indeed. linux_base-* are missing libgmp.so.3 despite some apps that
maybe used within linux shell scripts depending on it. expr(1) usage in
particular is pretty common even though one can easily replace it with
$((...)) arithmetics and case/esac shell patterns.

  $ /compat/linux/usr/bin/expr
  /compat/linux/usr/bin/expr: error while loading shared libraries:
  libgmp.so.3: cannot open shared object file: No such file or directory

  $ /compat/linux/usr/bin/factor
  /compat/linux/usr/bin/factor: error while loading shared libraries: libgmp.so.3: cannot open shared object file: No such file or directory

However, the quoted error wouldn't occur if:

  - the script is executed by linux shell
  - linuxulator strips /compat/linux prefix before giving up
  - PATH environment variable contains /bin before /usr/bin

  $ /compat/linux/bin/bash

  bash-4.1$ PATH=/bin:/usr/bin which expr
  /bin/expr

  bash-4.1$ PATH=/usr/bin:/bin which expr
  /usr/bin/expr

To fix try default PATH or file a bug against emulators/linux_base-c6.

The code assumes *ARCHITECTURE assignments never fail. In your case
TORARCHITECTURE is unset which leads to:

  $ /compat/linux/bin/bash
  bash-4.1$ [ 32 -ne ]
  bash: [: 32: unary operator expected

libcanberra dependency is optional and mostly used for theme sound
effects and notifications (e.g. alarm, new mail). As there's no
audio/linux-*-libcanberra dlopen(3) always fails for linux-firefox,
linux-tor-browser, etc.

Be careful with PATH and linux_base-* ports are known to provide
only complementary environment not enough to chroot(8) into.
