As I wrote, there is no "preferences" file on my
system. Create from scratch?
Besides this, what happens to the libraries if I free
a package? For example, I wanted to check the stage of
development of ghemical on GNOME, though it ptretends
to install mpqc too, which is not compiled for the
libraries I need (in part lower, in part lacking).
Thanks for answering
