+This is a history of my attempts at running tahoe-lafs in a fresh pogoplug v4 with archlinuxarm:
+
+Preparation:
+```
+# #Can't go straight to building v1.10 from source without gcc, so go for the AUR-based package to get dependencies installed 
+# #Install an AUR helper, python and build tools
+# pacman -S yaourt python2 gcc patch
+.. snip ..
+# #Make 'python2' available as 'python'
+# ln -s /usr/bin/python2 /usr/local/bin/python
+```
+
+Installation:
+```
+# yaourt -S tahoe-lafs
+```
+
+This is the first list:
+```
+==> tahoe-lafs dependencies:
+ - net-tools (already installed)
+ - python2 (already installed)
+ - python2-zope-interface>=3.6.5 (package found)
+ - twisted (package found)
+ - python2-pyasn1 (package found)
+ - python2-crypto (package found)
+ - pycryptopp (building from AUR)
+ - nevow (building from AUR)
+ - python2-foolscap (package found)
+ - python2-simplejson (package found)
+ - zfec (building from AUR)
+ - python2-pyopenssl (package found)
+ - pyutil (building from AUR)
+ - python2-argparse (building from AUR)
+ - zbase32 (building from AUR)
+ - python2-mock>=0.6.0 (building from AUR)
+```
+
+Arch will then try to install each of these. Some packages do not list 'arm' as a valid/supported architecture, so you will have to manually edit the PKGBUILD file:
+
+```
+==> Continue building python2-mock ? [Y/n]
+==> --------------------------------------
+==> 
+==> Building and installing package
+==> WARNING: Building package as root is dangerous.
+ Please run yaourt as a non-privileged user.
+==> ERROR: python2-mock is not available for the 'arm' architecture.
+    Note that many packages may need a line added to their PKGBUILD
+    such as arch=('arm').
+==> ERROR: Makepkg was unable to build python2-mock.
+==> Restart building python2-mock ? [y/N]
+==> -------------------------------------
+==> y
+==> Edit PKGBUILD ? [Y/n] ("A" to abort)
+==> ------------------------------------
+==> y
+
+Please add $EDITOR to your environment variables
+for example:
+export EDITOR="vim" (in ~/.bashrc)
+(replace vim with your favorite editor)
+
+==> Edit PKGBUILD with:  vim
+
+.. [edited PKGBUILD and manually added 'arm' to the architectures] ..
+```
+
+The same happened to the following packages:
+```
+pycryptopp
+zbase32
+zfec
+```
+
+Eventually, all the dependencies will be installed. But my tahoe-lafs installation fails to complete because of some error:
+```
+==> Continue building tahoe-lafs ? [Y/n]

+
+Will try in an arm virtual machine with more memory. Stay tuned.
