Doesn't handle linux distributions that use lib64 instead of lib.

OpenSUSE is an example of such -- lib/ is used for 32-bit libraries & binaries, and compiling Ruby from source will make a 64-bit binary, so it's configured to use lib64/ instead.

Got a good idea of how to detect this?

There is my commit to rbtrace but that requires loading Ruby, which I don't know how performant it would be. However this is a pretty much guaranteed to never change, so perhaps doing it on the first installation and caching the result?

Ah, and I've installed JRuby which uses lib/ and not lib64. Perhaps then doing that once per installation?

Here is a naïve patch that seems to work for me:
