Does anyone know if similar issues exist in the WRF-NMM code being used
for NAM-WRF?

Yes, it is a known change in BMJ, that they reduced its activity in
2.1. For 2.2 they are restoring a lot of its
old activity. I found out how to modify the 2.1 code to do this in a
quick way, but you need the 2.2 version
for the official NCEP change,

I'm trying to install WRF-SI on a machine with Red Hat Linux and the
Intel 9.0 compilers. Here's what's happening:
# perl install_wrfsi.pl --machine=pcintel
<blah, blah, blah>
Do you want to install the WRF SI graphical user interface? [y|n]: y
<blah, blah, blah>
Make and install wrfsi binaries in /home/training/WRF/wrfsi

Any ideas?
Thanks.
