Spot on.  What happens is that

  a) the Debian package system updated GSL via libgsl* to the gsl-2.*
  =

  b) the R package manager knows nothing about it

which why the latter couldn't tell Rolf; R's gsl package just fails to load.

In a fully integrated system a) can trigger b) and smoothly update the _R_
package gsl as a consequense of the _Debian_ library gsl changing. (That's
how Debian works internally.)

Here our coupling is looser.

The only remedy, sadly, is a bit of "been there, done there" which is how
Kirill spotted what to do.  =
