When linking, you use -lm, and not -llibm. In dlopen, you use the full name (libm.so).
After a quick look at ctypes reference doc, it looks like there are some function to search a library, maybe this can be used ? Anyway, this is kind of nickpicking, as ctypes is really a breeze to use. To be able to do the whole wrapping in pure python is great, thanks !
