[ Solved ] R 2.7.2 fails to load some packages

Question

Hi,
I was trying to install some R package from CRAN. For example "Hmisc" or "sp". Installation (through install.packages() ) was ok, but then ...
> library("sp")
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  impossibile caricare libreria condivisa '/mnt/data2/Rlib/sp/libs/sp.so':
  /mnt/data2/Rlib/sp/libs/sp.so: failed to map segment from shared object: Operation not permitted
Errore: caricamento pacchetto/namespace fallito per 'sp'
> library("tripack")
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  impossibile caricare libreria condivisa '/mnt/data2/Rlib/tripack/libs/tripack.so':
  /mnt/data2/Rlib/tripack/libs/tripack.so: failed to map segment from shared object: Operation not permitted
Errore in library("tripack") : .First.lib fallita per 'tripack'                                             
Other packages were successfully loaded, such as:
> library("RUnit")
> library("RColorBrewer")
Any hint/clue on what's happening? Anyone else using R out there?

You probably just need to rebuild it against the current version of your system libraries.
Yo, nevermind, it was my fault. As you probably saw in my first post, I installed the R packages as normal user (not root) in a partition mounted as /mnt/data2. I just had to add 'exec' to that partition's fstab entry, remount, and the problem was solved. My bad: I've lost 2 hours trying to figure it out (complete reinstallation of R and of a bunch of packages, which is not so fast on my old machine).
Bye, happy useRs!
