Did you get them from Debian, or from CRAN ?  I presume it is CRAN?

You need liblapack-dev with a version of 3.1 or greater.  You may need to point
apt to backports.org -- not sure as I do not run Debian stable (but only testing).

However the README on CRAN in the bin/linux/debian directory mentions
pre-built packages for r-recommended, so for mgcv you could

	  sudo apt-get install r-cran-mgcv

to get working.  You'd still need liblapack I suppose.

| Also, for r-cran-* packages, whether 
| update.packages(lib.loc="/usr/lib/R/library")
| is equivalent to apt-get install r-cran-mgcv etc.

Versions can be different between the two. It is a tradeoff choice you need
to make.  'apt-cache policy somepackage' will always tell you what version
you'd get from the different (if any) repos you are lined up to.  Doing R
directly via install.packages() is completely independent to that though but
should stay clear of trouble as non-overlapping directory trees are used.

Hope this helps, Dirk
