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.
