funky logging error when building WIEN2k due to file with funky name in install dir

[boegel]

During the installation of WIEN2k, the following logging errors are produced:

--- Logging error ---

These are caused by a weirdly named file:

$ ls -lrt WIEN2k/19.2-intel-2020b/SRC_nmr | head -2

These logging errors are annoying, but they're not fatal: the installation completes correctly.
