Other than that, I can't reproduce the problem locally - it installs for me whether built using the XC10.2 command line tools, or my own (GCC-8.3) toolset. ... is there anything more we need to do on this PR? (very happy to help, but not sure how to make pogress without a reproducer for the issue).
