This did work, so far.

I tried to do so, but couldn't find the edit-button.

For someone more wiki-proficient then me, here are the changes I would
make:

- in order to install the basic gcc, mention that -gnueabi is no
  consistently used across the architectures and that in case of doubt,
  an apt-cache search for that architecture, and within, for gcc or g++
  may help. If this is a sid-installation, the repository for squeeze
  (the regular one, not that of emdebian) is needed.

- although a link to backport instructions is provided, adding a
  line like

        deb http://backports.debian.org/debian-backports \
                squeeze-backports main

  may be helpful for people already having many pages open.

Probably not necessary to mention, that xapt needs -m for sid, unless
the reader is as ignorant as myself not knowing what is wheezy.

I did expect troubles heading my chair, so I'm very grateful for
debian's efforts.

I will have a look at Thibault which I didn't even notice when googling
for cross-compiling under debian. OTOH, I would have expected new things
to work on sid before on squeeze.

Cross-compiling for powerpc is not my main activity on this computer.
Also, the -m switch almost worked, but it seems that dependencies are
not followed (as on squeeze), so in order to get libpq, I'll have to
prepare a libssl, etc. Adding these libraries manually did the trick.
So, here is one more happy debian user.

Thanks for your time,
