libtool failing to load a library

Question

Can anyone provide any insight or way to debug why ltdl is failing to load my library? As you can see from the partial strace output it succeeds in opening the library, then reports file not found, and then moves on to successfully load another library built the same way. How can I debug this? I have been googling for ages and found no useful ways of debugging it.
