Sorry, I confused Hmisc (which I have been maintaining in Debian since long
before it was on CRAN) with Design.  Hmisc is of course still in Debian and
Ubuntu; only Design was replaced by rms.

| | 
| | /usr/bin/ld: cannot find -lquadmath
| | 
| | libquadmath exists on my Debian Squeeze system (up-to-date, recently installed):
| | 
| | ldconfig -p | grep libquad*
| |        libquadmath.so.0 (libc6,x86-64) =>
| | /usr/lib/x86_64-linux-gnu/libquadmath.so.0
| | 
| | The problem appears to be that libquadmath.so.0 is buried in the

| | 
| | The fix is:
| | 
| | cd /usr/lib
| | sudo ln -s /usr/lib/x86_64-linux-gnu/libquadmath.so.0 /usr/lib/libquadmath.so
| |

| Nonsense.  Look at the compile logs of /hundreds/ of r-cran-* packages across
| /more than a dozen/ architectures.  They build.
| 
| Look eg at http://packages.qa.debian.org/r/r-cran-rms.html and click on build

| 
| Funny how it builds on all of our machines witout intervention, eh?
