[QE-users] QE installation with libXC

[Paolo Giannozzi]

It is a "feature" (!) of fortran modules: if you need to load a module 
together with a library that was compiled with that same module, you 
have to use the same compiler that was used in the compilation of the 
library. It seems to me exceedingly stupid but there isn't much that can 
be done about it.

And, by the way: never ever update your OS unless you really have to.
