[R-sig-Debian] libgsl.so.0

[Kirill Müller]

The error message mentions (perhaps not very clearly) that the shared 
library installed with the gsl R package could not be loaded. Chances 
are that the gsl package (and as a consequence the copula package, too) 
didn't work before you upgraded. This can happen e.g. if the dependent 
system library (libgsl-dev?) is upgraded.

update.packages() doesn't try to load any packages, which would be 
necessary to detect this scenario.
