[LON-CAPA-admin] installing loncapa prerequisites fails

[Neubauer, Paul]

I'm trying to configure a new (replacement) server for our lon-capa box. Using Red Hat Enterprise Linux Server release 7.4 (Maipo)

I have installed the OS and completed through step 4 from the doc at http://install.lon-capa.org/RHEL7_install.html
Including (in particular) the rhel7_loncapa_yum.conf

HOWEVER, when I execute:

yum install LONCAPA-prerequisites
.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I'm not sure that I want to "skip-broken" at least not without knowing whether I definitely do not need lapack-devel-3.4.2-4.el7.x86_64 or blas-devel-3.4.2-4.el7.x86_64.
This is brand-new system with a fresh OS. The "requires" and "available" lines look like the install ought to work, i.e., if 3.4.2-4.el7 is required and lapack-3.4.2-4.el7.x86_64 is available, I would think the install ought to be OK. I'm evidently missing something.

I don't want to continue and break something. Any advice appreciated.
Thanks,
Paul
