So you have one copy of the library in usr lib and one in usr lib 64?
I wonder if that means you have a 32 bit and a 64 bit version of the
library, while I only have a 64 bit version.

I wish I could try several different system configurations without
backing up a couple hundred gigabytes of FLAC and SHN files...

Thanks for the information about the symlinks.
