Inertia is why I haven't posted over there yet.  I'm still not quite to
the point where my pain isn't self-induced and needs to be reported as a
bug.

The rpm spec file says BuildRequires: lam >=7.1.1-5

My version is less than that.  rpmbuild processes the spec file and goes
on its merry way.

I'd expect it to do:

error: Failed build dependencies:
        lam >= 7.1.1-5 is needed by blacs-1.1-11.i386


If I set BuildRequires: lam <=7.1.1-5 and then run it, I get
error: Failed build dependencies:
        lam <= 7.1.1-5 is needed by blacs-1.1-11.i386

On the system:
rpm -q --qf='%{Name} %{Version}\n' lam
lam 7.0.6


I guess my question is: has anyone else run in to this problem and is
this bugreport-worthy.

This post was sent after great frustration in trying to get the thing to
build, before I noticed that the spec called for a more recent version
of lam (which isn't even in Fedora, so how do they build it over there)
than I had and WHY didn't rpmbuild stop me before I spent all that time.
