I think the problem has to be fixed in the libraries themselves, this
can be done in two ways:
- the library not providing an os abi tag should be changed to provide
one.
- the library providing an (outdated) os abi tag should not be provided.
As a consumer, here are the things you can do:
- Remove the os abi tag stripping the library
- Removing the wrong library, or replace the wrong one by the good one
- Use LD_LIBRARY_PATH with the path to the right library. It gets
priority over os abi tag.
