libRlapack.so ... : No such file or directory

Hi,

I tried to install a few packages and got hung up when Matrix couldn't
be lazy loaded. The actual error follows:

library(Matrix)

Loading required package: lattice
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared library 
         '/usr/local/lib/R/site-library/Matrix/libs/Matrix.so':
  libRlapack.so: cannot open shared object file: No such file or directory
Error: package/namespace load failed for 'Matrix'

I googled a bit, and found some related bug reports, but I can't
understand them. Any suggestions? Could this be related to switching to
the optimized atlas libraries, which I did earlier in the week?

Let me guess: you mixed and matched installations from Debian and
directly from CRAN?  Everything from Debian should be fine.

Check that you don't have the Matrix library in several places.

On my testing system all is fine:
