[gradsusr] libpng15.so.15: wrong ELF class: ELFCLASS32

[Matt Bunkers - NWS Rapid City]

Hi,

I'm getting an error message that cropped up out of the blue (might have
been a system update) and am having trouble fixing it.  I pasted the
relevant details below.  We are running RHEL8.  I had done something (that
I do not recall) to fix this last fall, but here it is again.  Any thoughts?
