You must have some unsatisfactory-for-programmers font that makes it
hard to distinguish lowercase-ell from capital-eye (sorry, I realise
English may not be your native language):

   dash capital-doubleyou lowercase-ell comma dash lowercase-vee

But, in any case, it seems that there is no libblas.a or libblas.so on
your LIBRARY_PATH.

I'm a bit lost here, on Debian 6 the situation with libblas and atlas is
confused or at any rate confusing; and the /etc/alternatives scheme is
weird. I find it hard to believe that uninstalling the plain libblas
means I have to uninstall chunks of Gnome!

But I have a working libblas and liblapack setup without messing with
Atlas. And I see that the Atlas package writeup says it isn't really
optimised anyway, being as it's highly architecture-dependent. So why
bother with it?
