Use R CMD ldd /usr/lib/R/modules/lapack.so to get an accurate picture.

I think you need to ask this on a Debian list.  The R developers do not 
recommend the use of an external Lapack library (and the Debian ones have 
had `patches' that were incorrect before now).  (See the discussion in the 
R-admin manual.)  In this case I guess that it has not been linked against 
the right set of external libraries for your particular machine.

Should work if you build R from the sources with the default options.
