Hi Piet,

sorry for not answering in more detail the last time. Let me make a few
additions (I cut some stuff from the thread, in order to avoid noise):

I have just set up the chroot to start building lenny-cran. It might
still take me some time though. In the meantime, I have updated the
pinning guidance in the README.

Great indeed!

As you experienced, this is problematic, as the dependencies in
etch-cran were tailored to etch.

On my lenny systems, tcl/tk 8.5 was not pulled by the sid R packages,
only the pcre from sid. Did you make any progress on the tcl/tk issues?

Is this OK now?

I tried a few other mirrors, and they are OK. I suggest contacting the
admin of the Utrecht mirror, and/or Stefan Theussl
<stefan.theussl at wu-wien.ac.at> from CRAN.

I hope everything is running well at your end meanwhile,
