Layla has already fixed it in svn. It is the unexpected consequence  
of a small
change I did yesterday to filb/inpfile.f90: if no input file is  
found, stop with error
instead of trying to read a nonexistent stdin and producing a  
confusing error
message later. Since there is a new call to "errore", modules should  
also be
linked. Some simple routines in PP (and maybe elsewhere) did not link  
modules.

There is a more general problem here that must be fixed when we start to
reshuffle directories (something that will happen this summer): there  
is no
longer any valid reason to have distinct Modules/ and flib/  
directories. They
should be merged, thus solving in the meantime the nasty problem of  
circular
dependencies between the two directories.
