Re: dynamic-link sadness

(It is a bit weird writing to “Tim,” but my last job there were three “Tim”s 
... even weirder)

I figured it out. The string argument on my system was the path to a symlink, 
the actual file was “/usr/lib/x86_64-linux-gnu/libm-2.32.so” so it won’t follow 
symlinks to load libraries.
