Soft-fail on ImportError when importing c libs #300

Closed rmarrowstone closed 1 year ago

rmarrowstone commented 1 year ago

I had seen a previous report of a user unable to use a release of ion-python due to an ImportError other than ModuleNotFoundException. I thought it was isolated to that instance, but a different user encountered the same problem but due to a misalignment of linked to vs runtime libionc shared objects.

I was able to reproduce this in test by moving the libionc.so I was using.
